Got it for half price, and it feels like a half priced adventure.
When the level is completed you come across a board style game similar to a board game, roll dice, and this is how you level up. Each level can be beaten in 5 to 10 minutes, and you can get through both the Light and Dark side of Albion within an hour and half with little challenge.
Fable heroes does add a few positives to the mix, but you need to weigh the options first. The achievements are easy to obtain, and has a total of 400 for your gamerscore. The other is you can transfer the gold from this game you earn to Fable: the Journey. All in all though I don't recommend Fable: Heroes at all, it's shallow experience that I doubt too many people will want to come back to. Do yourself a favor and download a better game for your buck.
