Honestly, if it wasn't for the numerous glitches, this game could have been great, it certainly had the potential to make a wave in the 3D market in my opinion.
To this day I still play KOF 2006 (aka Maximum Impact 2) and if they ever made a third I'd be all for it. My main was Mai Shiranui, she was very combo happy and I created some unique combinations with her. The only thing I could never complete on KOF 2006 was one of the Hard Missions involving Kyo Classic and Ralph, where you had to beat him with one combo (70% damage no less). There was no strategy guide made for this game so mission was impossible, I still try to beat it occasionally anyways lol.
