I bought the Diablo clone "Torchlight" the other day for $3, and played till around the point where I found I could literally go fishing in-game while my horde of summoned minions fought the monsters. It really is "Progress Quest".
By the way, I tried Dungeon Crawl Stone Soup recently. Interesting races and classes, but I don't like having a game be all dungeon, no plot or character, with a strict timetable based on your reliance on dungeon food. "Elona" has more of a story and an overworld, which is nice, but has the typically horrible Roguelike interface.
