Can I sell a computer game that is based on a real board game? As a group of friends we started coding a computer game based on a board game called A (insert a board game, like monopoly). There are already digital forms of the game around made by the original owners (like hasbro). Are we legally allowed to sell (or giveaway, since we don't know if we actually want to sell it or release it as a free game) copies of our game which basically has the same rules/mechanics of the board game it is based on. If we can, what do we need to look out for when releasing the game? I heard names are subject to copyright/trademark, that means if we name our game A the Digital Version we'll get in trouble. We want to know what not to do when releasing our implementation of the game. Why we are asking if this is copyright infringement is because we are only &quot;copying&quot; the rules/mechanics of the game, while all the art/music/code are done by us. Does this count as transformative? Is this allowed? If simply &quot;copying&quot; the mechanics do not count as transformative, is adding or removing to/from the said mechanics count?
You need to check if the original game developers patented the mechanics/rules of the game. For your example, Monopoly was patented, but expired in the 50s and while it would not be a copyright violation to mimic the rules/mechanics, it would be a different intellectual property violation (patent infringement). Spry Fox vs LOLAPPS is also relevant as it extends copyright protection to the implementation of an idea, but ideas (like rules/mechanics) cannot, by themselves, be copyrighted. This means that there is an avenue for the original developer/company to sue even if the visual/audible aspects are different, but the overall gameplay is the same. Also see Tetris Holding LLC vs Xio Interactive Inc. as it relates to the visual aspect of the game.
If the "Pokeball" image is copyrighted and/or a trademark of Nintendo/whoever makes the Pokemon games, then whoever put that image out there under CC 3.0 BY is in violation and can be sued and will probably lose, and you would be in violation and can be sued and will probably lose. Your penalty would almost certainly be less since your violation was "innocent", that is, you had no way of knowing that the "Pokeball" imagery was somebody's protected intellectual property. ... Except you kind of maybe should know that, unless whoever made the Pokemon games (Nintendo or other) put the image out there and you can verify that, that maybe this license could be bogus and you should consult with who you imagine the owner of that IP may be or an impartial professional who could tell you for sure. I'm thinking if it were me I would do a little more research - and maybe get a paid opinion - if I was really thinking about using this for any but private purposes.
Does a situation like this constitute breach of contract and/or a violation of advertising laws? No. There is not enough information that would lead to a finding of either. It is unclear how customers would be allegedly affected (if at all) by the release of a product at a different store, let alone where the goods or services at issue are digital and require no physical presence at a venue or premise. Except for very specific factual circumstances, a change of sales venue would hardly be cognizable as deceptive or unfair practice. Also, prior to purchasing or reserving a game, there is no contract between the public and the developer/supplier. Potential customers typically are not entitled to a specific performance by the developer. Even if [Phoenix Point] supporters' decision were provably based on the prospect of release at Steam, your description nowhere reflects that there was a mutually conscious exchange (or promise of an exchange) of considerations involving the parties' support of a game and the counterparty's release of the game at a specific venue. Absent that meeting of the minds, either party's reliance or expectation on the other is irrelevant. Generally speaking, the sole cruciality of either party's motives does not create legal obligations.
united-states The license won't let you sell the .stl file. Probably you have created a derivative work, which means you can't sell it without a copyright license (and the CC-A-NC won't do). If it were licensed under CC-A you could sell it without problems (you'd have to give attribution, of course). You could also sell it under the CC-A-SA, but once you do you have no control over the result -- anyone you sold it to could give it to someone else under the terms of the license. This could work, though, if it were (say) a commission and you only expected to sell one copy. I don't know what the situation would be with the physical objects printed under any of these licenses.
It is legal Because of the first sale doctrine a person may freely sell a copy that they legitimately own. Copyright preserves the owner's right to make copies - Copy-right; once they have made (or authorised) a copy then the physical embodiment of that copy (record, CD, DVD, book etc.) is personal property and can be bought and sold like any other piece of personal property. The prohibition on copying its contents remains.
Copyrights don't apply to the names used. You mean trademarks. You copyright your game and you trademark the name. http://www.reddit.com/r/gamedev/comments/11v69k/using_a_guns_name_in_your_video_game/ Basically, it wouldn't be wise to use trademarked names in your game. Even though it's unlikely you would be sued and even if you were, you could possibly fight it under Fair Use, but do you want to take the chance? If some gun company decided they didn't like how you used their name, even if they have little to no grounds for a case, they can STILL sue. Anybody can sue for pretty much any reason where there is doubt. If they have enough money to throw around, they can drag you through the mud, ruin your business and then just lift their lawsuit. They don't need to win in court, just destroy you. Keep in mind that even if you don't use the name, if the gun in your game is an accurate replica of the real thing, it could still be a trademark issue. EDIT: Something you could consider though is asking permission. You never know. They may simply not care. You might even try propositioning them to pay YOU to have their gun showcased in your game. It's not entirely uncommon for companies to be willing to pay for a bit of endorsement advertising.
Your issue is trademark, not copyright. If these other guys use their mark (product name) in commerce but did not register it, they have an unregistered trademark which you could be infringing. Between two users of the same trademark, the first to use in commerce wins. (There is a territorial component but with the Internet, meh.) If the trademark is registered that gives them a presumption of validity. Trademark infringement is concerned with consumer confusion. If someone uses someone else's trademark in a way that confuses consumers as to the origin of the goods, that's a problem. What this means is that if I make tires with the name Sportie and someone else makes soap also with that name Sportie there is not a high likelihood of confusion. Likewise a hotel in Washington called Runner's Cove probably doesn't infringe a shoe store in Florida with the same name. Fantasy games and fantasy books sold over the Internet? Sounds like a potential problem that you might want to clear up before the second book.
Cheating in video games is not against the law. (If it's not for profit) IANAL The legality of cheating in video games has already been challenged in a court of law. You see, Nintendo didn't want people to cheat. Fearing it would lower the financial value of their games if you can beat them in just a few minutes. It was argued in court that a video game is no different than a book. If you want to read the end of the book, skip to your favorite chapter or skim quickly through a boring part you can. The conclusion is the game is yours to enjoy in anyway you want. Nobody can tell you how to play your game. There's an interesting and short documentary about the legal history of cheating in video games by the gaming historian. Also it doesn't matter what the TOS says. TOS is not legally binding Good news: another federal judge has ruled that violating a website terms of service is not a crime. But there's bad news, too — the court also found that bypassing technical or code-based barriers intended to limit access to or uses of a website may violate California's computer crime law. However, I've read you can be sued for breach of contract, if the site can prove any damages based on your cheating. I found that answer here on Law.SE and they didn't provide a source so I can't verify if it's true.
