How to create a selectable map for a board game in Unity3D?
===

I'm starting with a board game in Unity like Risk, programming in C#, and I need a selectable world map to put the armies on each region and make it the game board. I have a Raycasting function to select each country but I need to know how to build the board and make the countries selectable.

I have a board like this: http://2.bp.blogspot.com/-vtEHvcmS-Ac/TtHk0IvsxoI/AAAAAAAAAnw/V6e_eGfmCac/s1600/Risk+II+Game+Board.jpg

And I want to be able to select the countries separately, like they're objects on their own. Do you know any ways to do that?

Thanks for the help!
