I own this game for PC, PS3, XBOX, AND PSP. So I can thoroughly speak for each version. Hands down the best version is the PC, but this was back when I was a PC gamer, and was used to the mouse and keyboard. The Xbox and ps3 versions are pretty similar, but the ps3 doesn't come with trophies. I do prefer controllers over keyboards just because it allows for easy use of the buttons. If I had to compare it to another game, it would be similar to Brothers in arms, minus the weapons sway. To this day, I still consider this game to be one of the best first person shooters of this generation.
I do enjoy using the squad commands, it adds more strategy to the game. I love the selection of weapons at your disposal, it has some of my favourite weapons. I've played through the entire single player twice, it doesn't have much replay value there. The terrorist hunt missions are my favourite, I played it more than the story mode. It simple, customize your load out and difficulty, pick a map, and eliminate all enemies. These can be a lot of fun, but do offer quite a bit of challenge. One wrong move, and it's back to the start. I only played a little bit of the multiplayer, it's pretty standard, but requires more of a strategy and team work. The graphics looked good way back when, but don't hold up as well.
The best part about this game is it's cheap now, if you can find it, buy it.
