One old game I'm very fond of is Penguin Adventure by Konami on the MSX. Really loved that game. It was just brilliant. Beautifully designed and programmed. It was a bit of a rip off of Super Mario but done in 3D with similar goals and end of level bosses, time restrictions etc and timed jumping but it worked exceptonally well and had bags of character. Just an incredibly fun game of its day featuring Konami's mascot Pentaro who was the hero in this game but the villan in others or just a background character sometimes.
