This may seem original... but for Gameboy's Birthday the theme was games! Yep we are really creative like that around here.
One of his favorite games to play is Heroscape. We got it for Father's Day last year. The neat thing about this game is that you can set up the playing field however you want. Then afterwards it is similar to Dungeon's and Dragons. The neat thing about it is that it is quick to learn and easy to play.
Look it's games on the computer!
