I was about to make a thread about a Soul Calibur Generations but I forgot about this one being made.
Anyways lets start suggesting for fun.
SOUL CALIBUR GENERATIONS:
-have 56 characters in total (originally 46 but the Soul Edge versions of Siegfried, Mitsurugi, Sophitia, and the SCV version of Mitsurugi would have different styles and some new characters for SCVI would be added)
-each character would have 2 critical edges (all except Ocladan and Edge Master)
-Story Mode being long as hell from the start of Soul Edge to the end of SCVI along with some giant boss battles and some cinematic boss battles. (not the button sequencing, just an interruption in the middle of the battle)
-Each character having 3 or 4 endings from their story span in arcade mode
-the Soul Edge clash system (FOR CASUAL PURPOSES!!!)
Here are the boss battles I suggest from each story starting from SCII to SCV
SCII:
Nightmare vs Raphael
Kilik vs Nightmare (the conclusion of the SCII story)
Kilik, Xianghua, and Maxi or Nightmare vs Inferno
SCIII:
Siegfried vs Nightmare
Siegfried vs Abyss
Zasalemel vs Night Terror
Siegfried vs Night Terror
SCIV:
Maxi vs Astaroth
Edge Master vs Algol (part of Edge Master's flash backs)
Ivy vs Cervantes
Setsuka vs Mitsurugi
Siegfried vs Nightmare (should be an EPIC conclusion to the SCIV story)
SCV:
Patroklos vs Tira
Patroklos and O.Pyrrha vs Nightmare
Algol vs Mitsurugi
Z.W.E.I vs Nightmare
A. Patroklos vs O. Phyrrha (Round 2)
A. Patroklos vs Elysium
Remember, I'm just suggesting for fun and for my opinion of a perfect SC game. Don't take this too seriously!
