well, it's in print, for one thing.Theovis said:What's it have to offer over 4th edition HERO?

truth be told, 5th Edition is 98% compatible with 4th. if you've already got a 4th Ed rulebook and you're comfortable with it, there's not a whole lot of reason to buy the new rulebook unless you really want to.
some of the powers were re-priced, there's some new maneuvers, and lots of example powers showing how to use the system in interesting ways (one thing 4th never really did well).
i'm glad i picked it up, though -- it's revitalized my interest in HERO.
