Best. PS2 game. EVER.
Played it for 11 years, never got bored, got to the point where I could play on a one man team vs 16 AI's on the hardest difficulty without breaking a sweat.
It's a bit sci fi, hope you don't mind, but fun none the less. I don't suggest campaign though, kinda sucks and no story. Just random missions.
