Hey, I dont know if anyone suggested it. But if you havent heard of or seen Stonekeep. It is a 1995 interplay classic that was far ahead of its time. It is possibly one of the best pure dungeon crawls i have ever played. Games today hold your hand, and secrets are kind of easy to find. Stonekeep on the otherhand, any wall can have a secret block hiding treasure it seems.
Some who have played this game say the same block on every wall is always the fake block, BUT!! I watched my dad show me a secret he found behind a block underneath a lamp which was the only one other than that same fake block I ever saw in those levels.
Stonekeep has no difficulty setting, and is a brutally difficult game. Saving often is essential. But i recommend it 100%. Its a 10/10 game for me, and is up there with the likes of any great classic rpg.
