Altered Beast (Sega Genesis, 1989)

The original arcade version of Altered Beast was a terrific game, and this emulated version is a pale, weak version of the game it tries so hard to be. The game's slow speed and the lack of a two-player mode are inexcusable flaws. The Zodiac's Bluetooth feature would have made cooperative play simple to include. But as if to rub it in, the game actually asks you, before starting up the game, to be sure you have disabled Bluetooth. In its incomplete, single-player state, Altered Beast is inferior to its predecessor and not worth buying if you're a Zodiac owner.
