Ultimate Brain games Now don't get put off yet, not only does this cart include versions of Chess, Backgammon and Checkers, it does them in style too. I have only seen the chess part of the game and can tell you it surprised me! The programmers have come up with a beautiful 3D chess game with thousands of colours and wonderfully detailed chess pieces. Not only that but the game will have plenty of functional sound FX and even a multi-level chess game to tax your brain that little bit more. Also, the two player option makes this one a bit more interesting than its title. Look for this in March 95.

JEO: What became of Ultimate Brain Games and World Class Cricket?
TLG: Development was suspended when it became obvious that Atari was going to exit the market. The next question would be if they could be completed now. The answer to that question is the same that must be given regarding all future releases: it must be financially feasible for us to bring additional products to market. The sales results of the six announced products will determine if additional products are brought forth.
