DiabloRL is a relatively simple (as for a roguelike) attempt to mimic the game Diablo by Blizzard in the roguelike fashion. Might be considered a Coffeebreak roguelike. It is only basically finished, and probably will not be developed anymore. The game mimics Diablo's rules to the letter (except for realtime).
Due to the 7 day time constraint the game offers content similar to Diablo's Pre-Release Demo -- there is only the Warrior class, there are only 4 big levels to explore, and the game ends when you kill the Butcher.
This particular remake may be significant to some, becuase many wars have been fought on wether Diablo is a roguelike or not. Well, DiabloRL surely is.
