That's really it for me.

Gauntlet Dark Legacy.

Green Archer. That is all.

Killer Instinct 1 & 2. Come Microsoft & Rare if we aren't going to get Killer Instinct 3 then at least bring 1 & 2 to XBLA. Those two games would be top sellers immediately I would definitely buy them that's for sure & I'm sure a lot of other people would too.

And this why you are one of my best friends. I never played the other one, but knowing your taste, I'm sure it's good.
