If you're familiar with the original Rogue that the roguelike game style derived from you'll never find quite as true a modern take on it as Quest of Dungeons. Much more bare bones in both complexity and presentation than flashier flare Quest makes up for that in satisfying challenge true to the original Rogue and well-suited to more casual play on the cough. That isn't to say it is easy, in particular defeating the last Dungeon is a supreme challenge to your skill and your patience.
