Apples-and-oranges department... addictions are fun!
Unlike, say, Tetris, and all those other puzzle-play pimple-pushers.
Something strange thing about this whole situation is that the Columns puzzle-game series was a Sega arcade franchise, and Columns III was developed as a Sega product, but this Genesis cartridge was ultimately released and promoted in the US by Vic Tokai Inc. Perhaps the line had begun to run out of steam by this time, and Sega couldn't be bothered to bring it to the States on its own.
But at least it won't give you zits. You should buy it.
