Update: I really enjoy it. One of the few oldschool KOF's with good controls. Only problem; really hard to get supers out, but strangely enough I can get Terry's out most of the time...
Online was pretty good, I didn't feel any lag. Liked the layout and interface, very easy to set your controls, the Smoothing option for the sprites is recommended. Only downside is no training mode. My best characters seem to be: Terry, Ralf, and either Eiji or Iori/Kyo. Terry just has everything you want in a character, plus his tC is a great poke. Ralf is almost exactly like Clark except he doesn't have a running grab, however he does have probably the best CD in the game, that thing has big range. Eiji has a good mindgame, good combos, a reflector, the Reflector is also a good meatie as they wakeup, etc. Iori/Kyo are just easy mode. Andy is really good too, plus he has Rekka's in this game.
