But what about Metal Gear Federation Force?
I'd suggest selling it to Sony, but, uh, I'm not really sure there's anything left to do with the franchise. MGS4 pretty decisively ended just about every major plot point from previous games that wasn't resolved already, and while I'd enjoy seeing another Metal Gear Rising, I don't think it'd be worth purchasing the whole IP for that alone.
