Since a few people are just throwing out roguelikes they like, I figure I'd like to mention a couple that had an impact on me:<p>Incursion: Halls of the Goblin King<p>The mechanics, skills, classes, etc are basically ripped from DnD, which I've never had the opportunity to play, so I found it engaging. The author was touting the game as a sort of prequel/sample, just a single 10 floor dungeon, with the intention of using the engine to create a more expansive campaign, but then he moved on to other things, open sourced the project and abandoned it. Someone else forked it, but only to fix some bugs and improve playability, not to continue the grand vision. I think it still stands on its own as a worthwhile game, but its always been a disappointment that the full idea was never realized.<p>DoomRL<p>This one was actually a finished game. It did a good job of getting the feel of a fast paced shooter while still being a typical turn based roguelike. Things like being able to decrease the enemy's chance to hit you by moving perpendicular to their line of fire were a nice touch. I think they eventually started to get some pushback from the owners of the Doom IP, and pivoted to a new game called Jupiter Hell, that's supposedly the same feel with a different scenario, but I've never gotten around to checking it out.
