Seems like a good base for a SvC:C follow-up. I personally appreciate the addition of a story including a cut-scene before Orochi.
Some Pros and Cons so you can have an idea:
Pros:
1. A pleasant screenpack with a catchy intro and decent music choices.
2. Nice custom stages. I personally like the mid-boss stage with the ring elevating down into the temple beneath.
Cons:
1. Some pics like portraits have taken a hit through indexing (Notable examples being Gouki, Rugal and Blanka). I'd understand if it was to be authentic, but 1.1 allows non-indexed pics though SFF v2.0.1.0 if you don't know.
2. Playstyles for chars are inconsistent. Some have Supers that require low health, some have System Mechanics that some don't (e.g. Power Charge or MAX Mode). Zangief also has Mode Select. Orochi's a KOFM edit (Ember Eputh).
3. AIs are also a bit inconsistent. Because most don't have AIs coded, Ken and Sakura don't attack, and those with Power Charge spam the latter without defense.
4. It's kinda dull to have exclusively Street Fighter and KOF chars so it doesn't really spark the name. The other SvC games had Darkstalkers and Samurai Shodown chars for your interest.
