Game franchise with potential that isn't taken advantage of

[Ultr]

Ill go with my games of generation ps2, and generation ps3

Zone of the Enders (PS2)
and
Vanquish (PS3)

These two games are masterpieces!! absolutely brilliant gameplay, story of zoe is awesome, vanquish sucks a bit, but is great executed.

I would LOVE to see more of those games, unfortunately they have one thing in common: Poor sells

btw cant wait for the hd release of ZOE!!

the way the ended vanquish... I really hope the bring on a sequel!
