I think the series is getting repetitive.  I've played 1 for PSX, Director's Cut for PSX, 2 for PSX, 1 and 0 for GC.  Never played any Code Veronica, or 3 : Nemesis,  but if Zero is any indication I'm sure it's the same old thing.  And I'm a huge fan, bought the superbit edition of the movie (which wasn't that great either) and everything.   Sure the 2 char co-operation and switching is interesting, but the environs seem the same. I just started disc 2 of Zero, though, can't beat the bat yet.  It might get a lot better now on or something....
