Finished the game with 75 hours! (some are from the training mode, the encyclopedia and fight until the last goon is defeated before fight the bosses).
+ The gameplay is really improved in PxZ.
- The
plot of NxC is better than the
plot of PxZ.
- The transitions between games are less random in NxC than in PxZ.
+ The cast is better in PxZ. Capcom is better in PxZ (Dante, real RE characters, Devilotte, Batsu..., but not Haggar and Strider), Namco is a hit and miss (still Valkyrie :3 and Heihachi, but we lose King, Klonoa and the retro arcade cast like Taizo Hori -DigDug-), Sega is new, but in general the additions are awesome (Bruno, Ulala, Sakura cast...)
In the bad guys side, some are cooler in the prequel (Bison > Seth, Saya > Due, Skeith, God Eater's monster and others are boring), others like Lord Raptor are great in both, and some of the new baddies like Ciceraux or Vile are great additions.
But, the major point that make PxZ better than NxC is because
isn't there.
