You are talking about a game that was released in 2011. Crysis had no rival in 2007, were you a PC gamer back then as well? If you're complaining about high system requirements I bet you didn't play ID software games back in the day. Doom 1, doom 2, and quake made people go out and upgrade their computers. Crysis didn't even push the envelope as much as ID software did.
I still stand by the statement, no game in 2007 came close to crysis, it was a gamechanger. And a fantastic game as well. I personally don't care for bf3, i'm sick of military shooters because they are overdone. Thats beside the point though, bf3 is a 2011 game and crysis 1 had no rival in 2007 - it was a game changer, period. Crysis also still looks good to this day, something I can definitely NOT say for any other PC game released in 2007.
