Don't mess with the librarian!
As anyone who has played Spelunky or any other excellent roguelike (or, more accurately, games with roguelike elements) knows, death can come swiftly and without much warning. You can tread carefully though the world the game presents to you, surveying the area for danger, navigating your way around traps and hazards, scooping up every little piece of helpful loot along the way and, generally, just trying to survive, when, bam! A misstep can land you on an unseen set of spikes, or face to face with one of the most feared adversaries. Death can be sudden and unexpected, undoing all your hard work up until that point. But it is this perception of 'real' danger - the fact that death is final - that keeps you coming back to try again. When a game is a solid and enjoyable experience, randomly generated stages can be the difference between something you will play for a week, to one you will still be enjoying many months later.
