Deus Ex 3-
Well, I'm just about done. Game's doing a damn good job of engaging me so far; I feel like my decisions on augments and methodology both have meaning to them, and they don't always show what it was right away. Sometimes it's further down the road, when you're not expecting it. The environments are impressively large, and more than anything else, they feel more like actual cities or factories or offices, rather than "levels." Lots of things to explore and find, with rewards both tangible and intangible.
Weapons are all kind of suited to a specific thing, and you are of course free to augment yourself for more carry space so you can use more. Stuck mostly with the 10mm and the combat rifle, though I carry a sniper rifle for emergencies and a revolver for maximum coolness (and exploding bullets). The only design decision I really question is the battery recharge, where only the first recharges on its own, making expanding capacity mostly useless. All in all, even augmented all the way with dermal regeneration you can't just walk head first into a firefight, you have to think ahead and use your augs, the environment, and surprise to get the advantage against a group.
Plot is standard Deus Ex conspiracies, also loaded with foreshadowing of the first game. The hobo in the Detroit basketball court explaining literally the ENTIRE PLOT of Deus Ex 1 to a crowd was pretty goddamn hilarious. I realize that everyone has an angle and you can only trust your handler and your chopper pilot because it's fucking Deus Ex, but still seeing how everyone's plotting unfolded was, as usual, quite enjoyable.
Boss fights are tough but doable once you realize you should use the environs against them. Tried to take the first guy head on for a while before I started trying that and it worked like a charm. Also once you get the lift strength augment you can start using refrigerators as giant moveable cover while you throw barrels like Donkey Kong, which is fun.
All in all, unless they totally blow the whole thing in the last half-hour or so, I would say this game is a solid GotY contender. It is a game that actively tries to engage you in the gameplay itself, the metagaming that is using the limited amount of upgrades on a larger pool of available augments, and the game's plot. I recommend it unless you have taste equal to or worse than NEB's.
