With such beautiful graphics, you'll almost forget that it's about the gameplay. That's where Crysis fails to deliver.
The biggest setback of this game is that it played a bit too... I don't know, it just doesn't work all that well. Sure, the graphics are great, but behind that, there is a quite dissapointing piece of software. It's not that is isn't good, it's more that it feels like it's just another game with new graphics.
The interaction with the environment is probably the best part about Crysis. When you shoot at a tree (and there are a lot of trees in this game) it can fall down, if it's a thin one. But if you shoot at a very massive tree, one shot isn't enough. You got to take it down by using a more heavy gun, or just by firing a lot of bullets at it. These nice little details makes Crysis a very cool game to play for the first time.
Crysis does new things, and I can admire that. There for, I can enjoy a title like this even more than a game like Halo 3, which basically doesn't do a whole lot of new things.
If you know someone who says he has the best PC on the market, you can check that by letting him install Crysis. If his computer isn't sweating with all graphic options on MAX, it's a VERY strong computer. Please Crytek, make a sequel of this game, but then with much better gameplay. Less straiving can be a great modifier.
