resets aren't a problem, just kill a juiced dweeb, take their stuff, boom, you are now better geared than ever before
there are also low gearscore lobbies and a zero to hero gamemode where everyone starts off in similarly shit gear, this one is my favourite

the maps are randomly shuffled and other players are extra random elements that exist to give you a choice of will you make their day, or make it worse (or you ignore each other and go your way)
its a coffeebreak game in its nature

If you want something else, there are (this is a mixture of ancient and newer games):
Blobbers:
Wizardry series
Legend of Grimrock 1 and 2
Might and Magic series
Bard's Tale
Solo/Party:
Avernum and Geneforge series
Baldur's gate/ Icewind Dale
Divinity series
Age of Decadence (its not a dungeon crawler game, but it has some really awesome dungeons)
Thief 1 and 2 (its a stealth game, has some awesome dungeons/environments you sneak through)
Diablo 2, Path of Exile 1 and 2
Neverwinter Nights and nwn custom modules/maps
Djeryv' Tar's Ruins and Riches custom Ultima Online server
Treasure of Midnight Isles dlc for PF:wotr

ascii roguelikes or roguelikes with minimal graphics with nothing but dungeon crawling:
Sil-q (q stands for quality which I vouch for, lord of the rings dungeon crawl)
Frozen Depths (high quality, hard as hell, less than 10 people in existence have truly beaten the game, 2 of them are from 4chan)
Infra Arcana (lovecraftian dungeon crawler, high quality, its maker used to post on 4chan)
Frogcomposband (worth playing for its ridicilous build and mob variety)
Angband

there are more but these are the ones i thought of imediatelly
