The Killer Instinct series has to be the most underrated game ever being that the gameplay is absolutely addicting. Great eye candy, great sounds, gets your adrenaline pumping when you hit that perfect move. I believe the reason this game didn't gain great popularity is due to the fact that there is a long learning curve but Nintendo took that into consideration with the release of Killer Instinct Gold (which is basically a improved version of the original Killer Instinct with KI2 characters). Gamers can be lazy. I recommend you buy a N64 system with 2 controllers and this game. It will cost you about $300 less than the equal of a PS3 system or XBOX.
