International Karate Plus (IK+) was released in 1988 and was a massive hit on the Commodore 64, Amiga and Atari ST. I remember playing it on the C64 against my brother. It was one of the best karate games because besides the two players, there was always a third cpu player to go up against. The graphics were great for the Commodore 64 which only had a small palette of colors available and the graphic detail was great; the water would ripple in the background and birds would fly across the sky. The detail reminded me of California Games.
