What game took the longest amount of time to finish? Now, let's not count RPG's, unless they are simple and DON'T include a save or password feature. My choice would have to be either Ikari Warriors for the NES, or Rampage. What do you guys think? What other games took an insane amount of time to beat?
Edit: This only includes games that were made to be beaten in one setting (without shutting saving the game, shutting it off, and returning at your save point at a later date). This also (duh!) doesn't include games that don't end.
