Well,
here's Dark Alliance 2 (and
here's the original), not what I'd call much of a looker either, if we're being picky.

I have fond memories of Dark Alliance myself, for the co-op, but I've never had the courage to revisit it solo.
I think you're holding up too much on graphics, there's not a ton of difference between the games you're comparing as poor to those that are good. At least I don't see it.
Titan Quest I'll give you though, that one looks great. Too bad it got a bit boring for me, though I did finish it along with the expansion. You could try the Dungeon Hunter games, or the
Infinity Blade Dungeons if you want something a little flashier and aren't focused on depth/plot.
