I actually enjoyed all the CODs too, and I don't mean the multiplayer (that's what I bought Battlefield 3 for).
I've always been a big Nintendo fan, and don't mind at all that they're going a different direction than other console developers.
I thoroughly enjoyed all the Halos, and don't think Bungee ever "betrayed" their fanbase; gameplay tweaks that aren't successful aren't "betrayal," they just aren't successful.
I actually liked Resident Evil's new focus on smoother controls, and far from betrayal, all I find wrong with newer installments is lack of puzzles. Think: RE2 would've been just as awesome over-the-shoulder with good controls, if not more awesome.
I thought the DmC Reboot was good. It's Americanized, but that isn't bad. Dante is more punkish, but he is also written with more heart. When in the original series did you ever get the feeling Dante gave a flying fuck-demon [http://en.wikipedia.org/wiki/Succubus] about humans? He killed demons more because of his mom than any incentive to save the world. The new Dante looks off, but fits the story better. Hell, even Vergil gets the stupider-looking-but-better-written treatment. And the story is, if not better, at least more comprehensible. I do miss how often in the original series, demons would take on angelic appearance, Mundus especially. I don't hate the new demon-angel-hybrid thing for Dante, but I do blame Darksiders for coming up with the idea.
I liked Doom 3, what can I say? It's not a rock and roll shoot-em-up like the first two, but is that necessarily bad?
Duke Nukem Forever was okay. Not good, not bad, just okay. I play old shooters, and the nostalgia trip was fun, but they should've slashed the price.
I liked FF13. Guilty pleasure that I can't justify.
Metal Gear Solid 4 was my favorite installment. 3 was awesome, but 4 had feels. Oh the feels.
I can think Dead Space isn't scary and still think it's a good, brilliant game.
Dragon Age 2 actually FIXED everything that was wrong with Origins. It sucked not being able to choose race, but Bioware RPGs are stories, not sandboxes.
I actually didn't hate the original, unchanged endings for Mass Effect 3. I didn't like the starchild, but it didn't kill anything for me. An exposition from Harbinger would've been cooler, and your decision could be either in defiance of him (red and blue both) or compromising with him by picking green and accomplishing his mission for him without killing or enslaving his kind.
That's it for my confessions, which while are common apparently are neither mainstream nor vocal. Also, in the context of Skyrim exclusively as a standalone, Stormcloaks all the way! But... then I remembered Morrowind and Oblivion. FOR THE EMPRAH!
