There's way too many to list, but I'll have a go anyway.
Final match tennis - me and my brother used to have some epic matches, absolutely brilliant.
Super Tennis - see above
Moto Roader - great fun
X-wing - on the later missions, I would take care of shield duties and power distribution etc while my brother in law concentrated on the combat. It made for a really effective partnership and eased the difficulty somewhat.
PES 2 - me and my nephew would play for hours and hours.
Best of the Best - there was nothing more satisfying than being on the receiving end of a pasting, only to turn the tide in an instant with a perfectly timed spinning punch.
Double Dragon - for obvious reasons
Smash TV - absolute mayhem competing for the prizes.
