Deus Ex

The Good
Not being able to shoot as well when you're not as skilled in a weapon is a nice touch. The interactivity is the best i've seen since you can grab everything from houseplants to chairs. Then you can throw them on the ground to make a noise to attract the guards.

The Bad
The AI isn't very smart since you can pretty much hide in a ventilation duct and take out all your enemies without them being able to find you. I also hate it when you're in a conversation with an NPC and the enemies spot you. They won't shoot you while you're talking and will just stand there like idiots. Once you finish however, they'll kill you immediately. The game strives for realism but yet there are literally hundreds of crates filled with health kits and weapons lying around. The voice acting is only passable since the characters themselves don't sound very excited when talking. The way System Shock 2 worked was because the game made you lonely when traveling through the ship. But this game tried to make you think there's lots of government conspiracies which doesn't sound real and we never really feel like the governement's against us.

The Bottom Line
It's a combination of System Shock 2's RPG elements and Metal Gear Solid's sneaking around. Although there's too much shooting which completely ruins the stealth game because in a lot of the cases you can and sometimes wil be forced to shoot your way out of the situation.
