Nightmare is so un-fun I just flat refuse to play it.
I want to be entertained by my games, not to punch a hole in my monitor out of frustration.
Also, I find it kind of funny people hate on ME2 so much. In my opinion, it's the best game Bioware's made in years. People make the mistake of expecting it to be an oldschool CRPG just because it's made by Bioware--it's not. It's Gears of War without the suck and bad writing. It's Knights of the Old Republic where guns don't suck and nobody has lightsabers. It's a third-person shooter with RPG elements. Saying ME2 is bad because of that would be like saying Deus Ex is a shitty RPG because it has strong FPS elements.
Not all RPGs have to be isometric-view Infinity Engine clones.
