Delve!

Yes, this is a choose your own story... but it's also a dungeon explorer. The options you choose from are just related to defeating the monsters and making process towards the bigger prizes and even bigger monsters. If you're looking for an involved story with character development, this isn't the story for you (unless your mind wanders a lot while killing things). But if you want to hack and slash your way through hundreds of monsters on your way to glory, this is where you want to be!
