Hey, Archipelagos was quite good for the time. There were quite a lot of nail biting moments when you were trying to clear one end of an island only to find that the water had returned at the other end, cutting off the ability to destroy the rest of those monolith thingies.
It got pretty hectic and exciting in later levels.
I can imagine though that if you didn't have instructions or were too young at the time, the game would be useless to you.
Which begs the question: Is it OK for a game to be named as worst game of all time here just because someone was too young or played a pirated copy (see youtube clip) and consequently couldn't make heads or tails of it?
Other similar great games of that time could then also be unfairly mentioned: Towers Of Babel, Alpha Waves, Populous, or even The Sentinel, they could all then be ripped to shreds.
