Human Revolution was a pretty solid game. The boss fights are absolute garbage, and the ending leaves quite a bit to be desired (as do the endings of most games that sell you on the illusion that your choices matter only for you to pick A, B, or C at the end), but the rest of the game is quite fun. The level design is spectacular in that it gives you multiple ways to get through each level depending on how you want to play. It's not quite as open-ended (gameplay-wise) as the original Deus Ex, but it's still a lot of fun. I typically go for stealth in games like Human Revolution, and the stealth is very satisfying.
