I fully expect to catch hell for this, but I'd pay out the ass for a path of neo sequel. I don't know what it was, maybe the slo-mo kicks to the face, but I loved that game to pieces and always kind of hoped they'd make another one to continue the story once the matrix mmo/ card game fell apart.
I wouldn't turn down another Limbo, either.
I liked Enter the Matrix a lot more. The combat was a lot better, and I feel like PoN fell a bit short in that regard.
