The Dark Spire for DS.
Basic Wizardry-style dungeon crawl. For extra fun, they allow you to set it back to Wizardry-style graphics (no decoration, just straight lines for walls and the like, little 8-bit sprites to represent creatures).
I thought it was sorta fun, and then during the tutorial, my thief couldn't unlock a door. After the second try, the game's narration window then said:
A faint click is heard. "I've unlocked it for you, but pretend you did it yourself, okay?" Now the party must play a degrading game of make-believe.
I love this game.
