Well, I already had enough FGs to play (Blazblue, Soul Cal 5, Marvel, SFxt) but I bought KOFXIII today.
I keep hearing pro players say how this is the most proper, hardcore fighting game released this gen, and I agree. I can't call myself a FG player without owning it. I like watching KOF on stream (those HD combos!) and I guess learning the game will enhance that experience.
I'll be spending time mainly in training mode, as this is my first proper KOF. If anyone wants to play and teach me the game, just send me a message on PSN. However, I fully expect the netcode to be crap.
I also have to decide on a team. I like Terry, Maxima, Kensou, King, Joe, Andy and Ralf from the videos I've seen.
