Most of the stuff I wanna add is for CaS.
Add:
-Team Battle
-A Charade-like character. I think SCIII had one of those, it was that owl guy, why stop with IV?
-Being able to customize Algol, the Star Wars characters, and bonus characters' appearances. (Pink Yoda, or Shura dressed like Link...XD)
-ALL 1P clothes in CaS. Why just Amy?
-Skull heads in CaS. Hey, ToLS makes you fight skeletons, I wanna play as one.
-CaS Voice option with no dialogue (Think Voldo or the skeletons in ToLS)
-CaS-unique movesets (Never played SCIII, but I heard it had some cool movesets. Like dual nunchucks.)
-CaS Bonus character weapons. Shura's dual katana=DO WANT
-CaS ALGOL MOVESET
-Not Necrid. That guy sucked.
Remove:
-YODA. I'm fine with guest characters, I like the Apprentice, but Yoda's IMMUNE TO GRAPPLES.
-Tone down the stat-altering...or better yet, remove it. I guess they were trying to go for realism, but how do furry gloves/boots grant MORE health (Hero equipment), while FULL ARMOR gives you less? (Paladin equipment) I guess it slows you down, why not have it affect THAT? Or...nevermind. Remove the stat thing. The older games didn't need it.
