Of course you had to bring up Rise of The Robots again. The nightmare just never ends.

Broken games, I think Days of Thunder is one. Not buggy, just terrible. Looked ugly, ran unbelievably slow. Amazingly, two of my most favourite games are also two of the buggiest on the Amiga: Moonstone and Frontier. You could complete a game of Moonstone without it hanging, but it would often freeze. And in Frontier just travelling to a planet in a different system meant saving the game three times to at least two different files, just in case; pre-jump, post-jump and pre-docking.
