Kingdom's of Amalur: Reckoning. A very underrated game due to the fact that it came out near the release of skyrim
Definitely underrated. The MMO-like quest design didn't do much for me, and the level progression around the middle is pretty off. Other than that, I really enjoyed KoA, especially the combat & character building. I would definitely recommend the Dead Kel DLC as it was really good. The other one was kind of a 'more of the same' thing, so I guess getting that would depend on whether you've burnt out by that time.
Its too bad the studio went under. I wasn't really looking forward to the MMO they were working on, but I would've been interested in seeing what else they did.
