hi everyone. i have bought new pc today, finaly, and i think it will have no problems with any new game, so please are there any really good 3d games, where i can walk through the city and drive cars, like in gta? i am not a big fan of games but last game i played was from 2002 so i wil be glad to check how are games these days. any up to date gaming server is also welcomed. thanks in advance!
