First of all one has got to differentiate. While both those games you mentioned are dungeon crawlers with spatial (grid based) movement, that's also where the similarities end. The most defining (and maybe the oddest) features for roguelikes are random content generation, permadeath and turn-based movement. None of those are present in LoG (all of them in Dredmor, permadeath at least through an option).
So, if you are looking for old-school, first-person, grid-based RPGs like LoG I can obviously also recommend
Dungeon Master and
Eye of the Beholder (maybe the biggest inspirations for LoG). Something slightly more modern would be
Lands of Lore (one of my favourite games ever). If you don't mind having no party, but making your way with one single character you could also take a look at
Anvil of Dawn (the best graphics of the old ones).
If you want to play a roguelike on the other hand, there's the obvious recommendations (also known as "major roguelikes"):
ADOM,
Angband,
Dungeon Crawl Stone Soup,
NetHack,
Tales of Maj'Eyal (or "ToME", immensely polished, great UI!). Those are big ones, pretty complex and can be hard to get into. For some tighter experiences, check out
Brogue (best looking ASCII ever) or
DoomRL (it's like a roguelike-shooter) first. And then there's still so many unique games in this genre, I could spend hours going on about them...
A last hint: If you want to play a combination of the two kinds of games mentioned, try
DungeonHack, a first-person roguelike. Hope you find something worthy!
