Thanks!
Last night watched small documentary about making of COD game. It's really impressive amount of work put in the game to make it so authentic. (Game artists were send in 8 cities in Europe to make realistic building drawing, sound artists recorded real sound of weapons, etc...)
So I decided that I should try one of the games, and this will help me decide which one. (And if I like it, I’’ probably will get other titles too
)
