Colossus 4 Chess brings a lot of promise with it. It heralds itself as being the greatest 8 bit chess program available, but I feel I have to disagree. The old PSION Sinclair Chess program was pretty fab but I feel that PSI Chess is the best 8 bit chess game around. Colossus Chess has all the features of most of the chess programs about. it boasts 16 levels, which is quite impressive, and to be honest it does provide a good challenge. The screen layout is clear and in 3D perspective (or 2D newspaper style if you want) though still lack the 'cleaness' and finish of some other programs. Altogether, a very good attempt, but I can't see sales booming, not at this price anyway.
