No problem, the generic feel of the dungeon has always been the low point of Angband as i follow many discussion boards related to roguelikes it's the part that come out the most often when people tell why they don't play angband, in this thread already you can see some people mentionning it.
It's sad because the Angband gameplay and the ruleset are very good but the bland dungeon makes it very hard to keep being invested in the game until you reach the interesting parts and the challenging enemies that add this level of pressure on you that involve you into the game instead of boring you (the most fun i had in the past with Angand was when i started to dive in deeper floors, it was like a very different game from what it was in the 10/15 first floors as the blandness of the dungeon started to disappear in front of the challenging encounters you had there, a bit what Sil-Q is from the very first level).
But more variety in the dungeon could sure be helpful in breaking the blandness, looking at the early game of Brogue dungeon generation that is filled with different terrain and tons of dungeon feature could be a good idea as that keep the player interested from the start .
Thanks for pointing those variants, there are so many of them
EDIT
started to play a bit of Composband, it reminded me a lot of zangbandtk , that's a good thing
Completed a couple of the easy quests and after getting the 3rd done (a pack of wargs in one of the depth of the dungeon) i got rewarded by a very good and at the same time a very horrible weapon
the aggravate wasn't really that scary as i was only level 12 and so far was butchering everything coming my way, it would be a bigger problem later, assumign my guy survived of course.
But i overlooked the "Ancient Foul" words when reading about Curse so i just thought about the switching weapon problem.
And that was really really horrible.
While adventuring more i started to be sometime teleported around and losing stats points out of nowhere.
I went back to town the hard way (as i completely forgot to buy more word of recall as i had none left) , meaning a few more stats points were lost.
As it was cursed i couldn't switch weapon of course, this i understood when i equipped it as i remembered the "Curse" word, but "Ancient Fool Curse" isn't that kind at all, as after buying a remove curse scroll to be able to switch weapon, it didn't worked the way it should have.
The thing teleported me outside of the town, landing at some distance in the wilderness, right inside of a river (so i was drowning) while being surrounded by a lot of spiders and a "greater hell beast" (no idea if it was the same inside joke that greater hell beast was in zangband)
Died very quickly to that.
Lessons to learn, when you read "Ancient Foul Curse" , do not overlook the words "Ancient Foul"
