I preferred ME1 over ME2 also, I felt more IN the game with the first one while ME2 just had prettier (ok, awesome) graphics. It just had too many immersion killers for me to really enjoy it like I did ME1.
Oblivion - won't go there.
Dragon Age, nice game in there somewhere. It had some really emotional scenes in it that could really get to you, but it was so tedious to get to them....
