I was a big fan of Eye of the Beholder 2 back in the day. I spent a lot of time skulking around in the sewers of Waterdeep, and falling victim to all sorts of traps and monsters. It was fun. I miss those old, first person style dungeon crawlers; the last one I remember playing was Wizardry 8, and that was at least seven or eight years ago. Anyway, looks like some developers share my nostalgia for games like this, because they're making a throw-back RPG called Legends of Grimrock. It looks pretty cool, and might be out (I hope) by the end of the year.
Here's some gameplay footage.
