Sega Master System / Mark III / Game Gear
Featuring superb presentation screens and a beautifully balanced difficulty level, American Pro Football is the finest simulation of the sport on any 8-bit machine.
The graphics are tremendous, and there's great joypad feedback which really draws you into the action.
A system of menus are used to dictate play, and while they offer an amazing array of moves, they're very simple to operate, so a novice can get straight into the action, but have enough variety to let experts develop complex plays depending on the situation.
The graphics and sound are both great, and the highly addictive gameplay is the icing on the cake. An absolute must for sports fans everywhere.
