I remember spending hours as a kid during school holidays playing Park Patrol on the Commodore 64. There was just something really addictive about running around collecting rubbish whilst trying to avoid being attacked by dogs, people, snakes or just about anything else that could move! Also on the C64 was Mayhem in Monsterland which had amazing graphics (for the C64 anyway) but I could never get past the first level, plus it took days to load off tape...
