I've mostly been put off Dwarf Fortress by what looks like an insane learning curve. I just wouldn't know where to start.
On the other hand, Liberal Crime Squad looks fun and i'm thinking of picking it up.
I've played and enjoyed plenty of games with low quality graphics. DF unmodded, however, has a learning curve just to figure out what's what. Case in point:Spoiler :![]()
Admittedly it's not so bad with the tile sets, but it sure ain't pretty.
