Thank you for the better 60 in 1 multi suggestion. There are SOOO many great games that be great on the 60 in 1.
And IMHO, the 100 in 1 board has nothing I'd want. I'd much rather have the other games we're talking about here, such as zookeeper.
And if you want to make a new multi and not a switcher, how about:
2 player multi (snow bros, WoW, etc)
and instead of the multi-jamma+, how about xx-in-1 4 player multi (Gauntlets, NBA's Jams, Quartet, Simpsons...)
Or a multi double trackball (marble madness, boot camp, blades of steel...)
Ok, one more xx-in-1
Multi-Track and Field (hyper sports, 88 games, etc.)
