??? best game for 20 age ???

I recommend any first person shooter game. Most games developed these days aren't really aimed at a certain age group. Take Halo 3 for example, I've seen many little kids play it as well as teenagers like me and as well as adults that sound like they are 40.

hi there. i am a multiplayer call of duty 4 player. it has great gameplay plus the fun is doubled when you actually play for a clan and have clan matches! i played this recently released game called Prototype and i find it pretty interesting as well. it is a free roaming game like GTA series but has a lot different story, where your city has been hit by some kind of virus which is mutating people all over. it's gameplay is somewhere in between devil may cry and GTA. i would definitely recommend you to play this game!

God of War, Mad World, Halo, Mario Galaxy
