The top 3 worst spectrum games ever as voted for on WOS. They are:-
3. Gobbler - 1982 Saturnsoft
2. SQIJ - 1987 The Power House
1. Kosmik Pirate - 1984 Elephant Software
The bottom two are just amazingly awful and I have no idea what was going on in either of them. I never got further than randomly mashing the keyboard for Kosmik Pirate but according to the inlay it "represents excitement for all the family (including addicted invaders players) and provides unending enjoyment" so I must have been doing something wrong.
