My own personal favorites include Batman: Arkum Asylum - the story line and game play is first rate. BioShock, another very immersing FPS. Bioshock II was "give me some more of that" and also highly recommended (if you enjoy sometimes being kind of terrified). LotR online and D&D online are both free to play (so you can jump on for a couple days every 6 months and not feel like you are being screwed by the man because you payed 6 months subscription). World of goo is very nice as is Plants vs Zombies and even kingdom for keflings is a hoot for a builder game.
Now to the question of whether you have lost your mojo... it is easy to see the game for the math that it is - a simple counter (if I click in the right place enough times, "I win" - whatever that means in a virtual game). Once you understand a game, sometimes the senselessness can make even the idea of the playing seem rather like a waste of time and so you project that feeling onto other games thinking you have been there, done that. But it's not true. Batman is completely different from any other game I've played - and completely changed what I thought was possible. With the new input devices (I'm thinking kinect here) and new display capabilities (3-D is pretty wicked on games that program for it), I think there are games coming out that will make even that pale in comparison.
