I'll happily pay $40 for Ground Zeroes.
I won't, for the greater good of the franchise, but I'm sure other fans will pick it up at that price.
I'm just interested in how good it is, and how it reviews. I can't see non-fans being very tolerant of a 4 hour $40 release, especially for a stealth game. At least in a modern shooter campaign it's an adrenaline filled, explosion packed, 6 hours.
It'll be interesting to see.
