Killer Instinct's 30th Anniversary of its arcade release is today!!
It was a total surprise when it showed up in my local arcade and it was just as big a sensation for us as Mortal Kombat at the time.
In the long run it didn't completely replace MK but I virtually love playing it just as much and it has aspects that I do think are better!
I remember the new toy syndrome other arcade gamers at the time where they only wanted to play KI and looked down at MKII and I could understand why but I didn't completely share that feeling. I never stopped loving the MK games! Even when my focus was KI!
