Getting into some "dungeon crawlers"...

I've found a growth of interest in these types of games after playing Diablo for a while. So, I got busy and looked up a lot of them and plan to get more. I just got the Diablo expansion pack, Hellfire (very rare I hear, lucky to find one) and I recently purchased Fate, another game similar to Diablo. Looks good too. I'm planning to get Fallout and Fallout 2 along with Diablo 2 and its expansion. Don't know why but I found a liking to these types.
