The problem I have with this game is that once you get the top-tier weapons and unlocked pretty much everything there's no challenge left for you to do.

Every played defender II on an android phone? That small tower defense game had increasing difficulty for each level you play, I'm at level 555 and I'm still enjoying this game. Your idea is great however the rewards should be a little less than that. If you obtain a set of the top tier-weaponry and armor once you beat the hard mode, the game will become too easy to play.

Of course for me because I don't have xbox-live yet and therefore no infinitely scaling hp with the online ur-dragon. But still, they need more enemies like that in the game. Think mmos.
