KOF series is one of the best 2D fighting series. So many characters with their own move sets and combos. Not as much repetition as the Shoto or charge characters but Id say it was more innovative than Capcom's games.
Roll, hop (HOP!), short/long jump, super combo, ultimate combo (red health), initiating power charges, blocking break, combo cancel, air blocking, tagging, Mai Bounce.
The Samurai Showdown series isn't bad. The 2nd is the best with the third behind it. It's also the only game where I can only beat (the 2nd one) with one character. The boss and extra hidden boss are stupid tough.
I really need to invest in a proper fighting stick.
