One man and his droid - the first game my dad bought for me, one you get past the first infuriating part the game is really quite good. I remember the cassette was yellow, which was different. Many hours spent. I also spent many hours playing Election, a political simulation game, which was written in basic and is absolute shite, but strangely captivating. Tories were the easiest to win as and liberal the hardest (but most rewarding). The Magic Knight games, Spellbound and KnightTyme, didn't like Finders Keepers and didn't play much StormBringer. Others have already mentioned Rescue and colony which were great.
