ELI5: did playing video games shape my intelligence and personality in a positive way?

Basically all my life (age: 27) I have played video games so I'm wondering whether they had any positive effects on me (especially on my brain) or they just robbed thousands of hours from me. I read it once that playing e.g. Tetris can have a positive effect on brain functions, but I wonder whether it's true if a grownup does it and not a child who is getting more and more intelligent by the years.

No idea. 

The studies are really variable because the things are very broad, vague and relatively new so there are more questions than answers. E.g., Do we mean specific games? Only violent games? Strategy games? What about when they overlap? Only certain methods of gaming, like PC or console? Is it only during certain periods this works? Is it related to playing particular game as particular ages, e.g., are violent games at 5 are bad, but at 15 are ok? If there is an effect, for how long does it last? Is there a threshold for when these effects begin ? Is there a threshold for when the become/stop being good or bad? 


It would be wrong to extrapolate those to say that taken together they have had a net 'good' or 'bad' effect on you.
