Splinter Cell Conviction
Gamers bitched about it being dumbed down and being turned into a pure shooter, both of wich a rather dumb things to say in my opinion.
While you CAN play it like a shooter, it's not going to be much fun and also rather hard on anything higher than the easiest difficulty setting (aside from the non-stealth-flashback mission that is, admittedly, rather sucky)
On the other hand however, you'll get options to play stealthy that feel much more diverse than in other games. You can still play the way you are used to, hiding in shadows, memorizing routes and taking down enemies unseen, you can lure enemies into traps or let yourself be seen to quickly flank enemies. And most important of all, if you a really good, you can clear rooms and setpieces FAST, oftentimes in under a minute.
Climbing, running and rolling from cover to hiding place to cover, killing guards up close and then finishing of the remaining enemies in a glorious quick-draw fashion like a hybrid between a ninja and Jack Bauer is one of the coolest things i could do in any game in the last five years or so.
Also, while the story could be better, the Protagonist was still more likable than "mindless goverment tool Sam" of the first three games, and it had a cool "direction"
Other than that, a honorable mention to Mirrors Edge, because i still very much like the game and am still very angry that it wasn't really successful because people deemed it too different or too hard (while calling the Cel-Shading Prince of Persia too easy. Gamers are weird like that)
