Im an old hat at KI. Id like to know what your refferring to? The changes Ive read about are needed changes, changes that make it better not worse. 

"Killer Instinct is looking to be a pretty promising fighter. It’s easy and quick to get into, but looks like it’ll have quite a bit of depth. And of course, the system of huge combos and combo breakers remains as intense and rewarding as ever."

"A week ago today I was able to get my hands on Killer Instinct for the first time. I have always been a fan of the series and one could say that this is my favorite fighting series of all time (next to Tekken and Def Jam). I was a bit skeptical about the new direction they were going with the series, but after playing the game I left impressed."

I probably will get the Ultimate edition.  This is the genre I love so I pretty much purchase every fighting game whether its on the PS3, Wii or 360.  Give me the full game, I do no need to experiment with with the beta character paid model MS is trying to do.

Microsoft were just first. Capcom are also doing it for all their new fighters and the new MK is too. Thank Android and Piracy for this. :)

Its an interesting concept and it has the ability to get more sales without someone commiting to spending 60 bones for the full game.  If Capcom, Namco, and other developers can tier pieces of the content like this, it might work.  Say you only play 2 characters and you want the practice and arcade mode.  If it cost 10 bucks, I can see people going for that.

Ultimate combos are coming. Danger moves are coming and theres talk of Humiliations to. We are getting story mode in February with added combos. 

Looks awesome. Reminds me a ton of the SNES KI I played the shit out of. Never played the N64 KI much.

Don't really care for fighting games in general. I had the chance to play the game at an Xbox One tour van thing, and it was fun for what it was though.

I think one of the major barriers for me is the fact that it is a digital only game. I can not justify dropping $40 or $60 for the pin edition for a game that doesn't even come with a disc.

Will pass for now ... probably will be a physical release down the road with everything and all DLC on it just like Walking Dead.

Im looking for the interview. But theres tons on Youtube. I'll find it if it kills me.

i will get the game and i know over 30 of my friends who are getting the game as well, plus this is a true killer instinct game and looks to keep the fire burning from what i can tell, i dont understand how ppl can say it isnt that. all i can think of why ppl are just bashing on the game, is simply because its a xbox one game and m$, simple as that.
of course this is just my opinion

True Killer Instinct fans will get this game Day One^TM . This game is about COMBOS. COMBOS and COMBOS.

It had the most fluid and complex combo system ever when it debuted in 1994. The LOOKS are not that important. And finishers, ultimates and humilliations? KI was not known by those features. It was always combos, combos plus combos, which look great on this iteration.
