Same gameplay is a bad thing. I just did not like Crysis' gameplay at all. In theory it sounds great, but actually playing it, it was dull and boring. The graphics weren't the problem at all and I think it would've played fine on older systems if people actually lowered their settings, but everyone wanted to play it on the highest settings even if their computer couldn't handle it.
Anyways, back to my point... the original just did not feel right all the way around. The suit controls were overpowered. Stealth, kill, stealth, kill. Sure, you could go out of your way to make it more challenging, but it still wasn't as satisfying as Far Cry. Plus, the guns felt extremely underpowered which made it all the more lame when they could take down trees. And the game lacked any blood or dead body manipulation. For a game that's striving to be realistic, those two things stuck out like a sore thumb. And houses felt like they were made from a deck of cards. You could run into a wall and the house would start to fall apart. So the graphics were the least of the problems, in my opinion. The graphics and steep requirements were probably its biggest draw.
But the biggest problems were probably the short and linear levels. It wasn't as long as Far Cry and it wasn't as expansive, and the cliffhanger ending sucked. And I really hated the aliens. Maybe I just hate squid things. I even hated the Matrix squid things.
I liked the different weapon attachments and customizing your guns and of course the graphics but that's about it. I'm more interested in Far Cry 2 right now.
