Magic & Mercenaries: Curse of Eternal Darkness is a game currently in development by ProphetSword that aims to emulate the classic Goldbox-style games from SSI that combined dungeon crawling with tactical combat. M&M:CoTD covers similiar ground, you have a 6-character party choosen from 15 classes and a fantasy-themed adventure with dungeons and cities to explore and many monsters to fight.

Of all the dungeon crawlers currently in development, the one I look forward to the most is Stellar Terminus. Here's the brief in the creator's own words, which I couldn't have summarized better: ST is a first-person, hard sci-fi dungeon crawler set at the heat death of the universe. You explore an endless sea of lifeless planets and abandoned megastructures, built and inhabited by various AI factions with their own style.

On the off-chance that you don't already know this; let me tell you about a very talented Finnish guy called Petri Häkkinen (@petrih3 on Twitter). Petri is developing a dungeon crawler for the VIC-20 (yes that's correct!) called The Fall of the Black Mage. What I have seen so far looks very promising and this game might turn in to something really special.
