The eighth voyage of Sinbad leaves a lot to be desired when compared to the first celluloid seven. This game is certainly original. That is to say, no-one else has bothered to waste time on such an idea before.
First, the scenario. This is going to sound stupid, but here goes anyway. You are presented with Sinbad's flying carpet swooping around the screen trailing a rope ladder. Also buzzing around are several malevolent life forms. You must jump Sinbad onto the ladder so that he touches these 'life forms' and converts them to peaceful ways. If he touches one already converted, he falls off the ladder.
When all that is done, it's off for a quick trip through an asteroid storm. If you manage to steer him through that with the awful controls provided, then you go back to square one with the addition of different life forms and other things like spiders.
Virgin has described this game admirably with its title.
