Dragon Age II burnt me pretty badly - those repeated caves/dungeons
That said, Witcher 2 wasn't something I 'loved', whereas I thought Dragon Age: Origins was fantastic. (Don't get me wrong, the Witcher 2 looked great and played decently, I just lost interest in it).
After what we've seen so far though, Witcher 3 has my interest more. That Dragon Age combat from the press conference was a bit unsettling.
