If you remember computer games like Dungeon Master on the Amiga or the Eye of the Beholder series, and that memory is a fond one...check out a new game by Almost Human called Legend of Grimrock.
Imagine that familiar grid-based movement with beautiful graphics and sound, tricky puzzles, and that "just a few minutes more" need to continue playing that turns into an hour past your bedtime? That's Legend of Grimrock.
After a few minutes you'll fall back into those old habits that kept you alive years ago: dodging in and out to attack, strafing to backstab, and dreading the flicker that means your torch is about to go out.
You can create your party of four however you like - race, class, skills. And if you are really feeling old school you can turn off the auto-mapper. Just be sure you have a nice stack of graph paper on hand...
