Code Veronica has so much more potential. First of all RE3 was limmited by the PlayStation and the environments are too claustrophobic for a city... they would have to change the game too much to where it is unrecognizable.
Secondly it is uncompelling story wise and was not meant to be a numbered title
Finally it mechanically will not work and turn into more of an action game. Dodging will make the game too easy for veterans. Nemesis will scare off newer players and just will be too hard to program.
