On top of my head, it would be these:
· Dead Rising. It's actually a damn awesome game, with an original story for a zombie game, some daring plot twists and a superb gameplay system (if you can endure the time constrains, but imo that's what gives the game a doze of personality). It spawned three sequels, two main entries and a spin-off. Both the second game and the Off the Record version are damn great as well.
· Dragon's Dogma. One of the best games I've ever played. It's a unique RPG, and there's nothing like it. Its clever, memorable ending stuck with me for some time.
· Demon's/Dark Souls. I'll stump them both together, though I played Dark Souls first. Two truly amazing games with an almost flawless design and incredible replay value, plus satisfying gameplay that keeps you coming back for more. Dark Souls is also one of the best games I've ever played.
· Gears of War. Memorable franchise, and the third game actually made me play multiplayer for a long time, which is actually quite the feat.
Now I'll proceed to name two different games, because I'm not sure the first one qualifies, as it got released cross-gen:
· The Evil Within. Fantastic game with an immersive atmosphere and visceral combat. Plot is weird as heck, and there's a lot of entertaining moments throughout a lenghty campaign.
· Uncharted. While the first one was an interesting, enjoyable affair, the second one was an amazing experience and a fun game altogether, with high replay value and one of the most memorable intros in videogame history. The third one is a bit weak, though, but the fourth one is shaping up to be fantastic.
