To be honest this isn't the sort of game I'd usually buy; I tried to get into Fallout last gen with 3 and I just didn't like it. Then again, that was a long time ago, tastes change with age (for example I didn't like Metroid Prime first time I played it, now I love it) and the setting here looks a lot more interesting.
If its a decent conversion and I found myself with a few months without any interesting releases I may pick it up.
