Do not forget IMANOK's ARM WRESTLING. Easy concept. Tough gameplay. A nightmare for your joysticks/keyboards. 2P mega action only!
[promo]And G-MONKEY is a nice 2P game, although it is turn based. Guess it would be a good option for user meetings![/promo]
And you also have the almighty codeless CURSOR GAME
The amazing CURSOR GAME is specially suitable for OCM, as you can just buy another PS/2 keyboard when your current one is fried up
"Missum" or "Missun" game from a compile disc station, really Quake for MSX.
Or Conecta 4 by internet.
Konami's tennis or Konami's Soccer...
very fun to play with my sons!!
Laydock was kinda funny as well ^_^
(high five to Sylvester @ 2006)
Penguinkun Wars 2
FLASH SPLASH (space shooter, three players)
You could try something like Akambe Dragon, alternating the characters from the game.
The Tower (?) of Cabin
