Crysis3s.com shows a grand total of 1000 or less people in game as of right now. Granted it's monday night (here) it's not too different on the weekends. What's keeping you from playing?
Personally, I think the game is perfect except for the running into teammates and dying.

need one more option,
never bought the game cause it was never on steam but now it wont even matter.

Take that up with EA (Evil Aliens) buddy. A lot of people got pissed when EA pulled C2 from steam.

Copy/paste from another forum:

It is getting a bit boring to me. It's not really challenging anymore.

Making kills is easy. most deaths are lame. The inconsistency is tiring. I don't even feel like restarting my xbox when it crashes anymore. Meh...

The game has been out for two months, and the Xbox version still freezes three times a day.
