FYI, Assault and Karate Champ both NEED 4-way sticks to function properly.
And spinner side is a personal preference.
Tempest and Major Havoc were the only two games that had it on the right in the arcade, and I never liked it there.
All the other games I played had it on the left (Star Trek, Blasteroids, Tron, DOT, Omega Race, etc...)
Also, driving games would be really weird to me with the "wheel" in my right hand.
