Probably some of the games I got for my Amstrad CPC. It's been so long since I even looked at it that I can barely remember any of them, but one that stuck in memory was a game called Roland In Time. It was a hard as nails platformer that ripped off Dr Who for its main character. I think there were ten levels and you could play them in any order, which is good because with most of them I could barely get off the first screen.
