Dwarf Fortress is an amazing management game in fortress simulation mode, but kinda struggles as a Rogue successor. The layers upon layers of simulation don't mesh into a very satisfying experience in adventure mode, imho.

Brogue is somewhat minimalist and very tightly designed. The design of every item, monster, and dungeon in the game is inextricably interwoven into a cohesive whole. It evokes very similar feelings to Rogue while also doing its own thing. Less "continued development of Rogue" and more "Unofficial sequel."
