I play Dungeon Stalker (first-person dungeon slasher) and was wondering if anyone can suggest some similar games.

Dungeon Stalker is pretty good, but once I get to level three of the dungeon it seems like it gets insanely difficult. Some other minor gripes are I dislike the magic system and it's tough to find healing potions.

Overall, I think it's a good game, but it's more of a personal taste issue.

Anyone have suggestions for alternatives?
