XIII is just the finished game XII was intended to be (except with the camera zoom removed) if they hadn't been forced to release it half-done. SNKP have said as much.
Yeah. From this p.o.w., one may say KOFXII release has been quite a wide beta testing for the new engine, which is also good. Zoom removing has to be listed in this regard, and I think that's for the better. Also K' team is most likely the only real 'addition' actually made for KOFXIII (settei could even be not from Nona, you may notice as all the three members of that time are way less extreme and characterized if compared to all the others in the game).
NEOMAXs, ES/EX system and other gameplay features are also very likely to be KOFXIII originals. Matter of fact,the game system has improved drastically from the very basical re-start of KOFXII, which seems to be a basis out of which SNKP started to rebuilt at least. The half-game it was, it has not been totally unuseful at least.
Also: Taiso and NeoAlec. You really have no need to quarrel.
You're both great guys with great love for the Neo franchise. We all kmow that. Apart from the way you speak at times, you both support SNK(P) games, you want theme to be good, and you enjoy them. You're really on the very same boat, together with me. A slight, occasional diverging in your personal stance/attitude towards what you like and support (or, towards the makers/creators) just should not set you apart. I know you know, beyond the drama.
