Can anyone list any games it would be natural to have TWO physical input devices (except gun games) that does analog
What do you mean by "physical input devices" you mean players or simply games that need more than 4 channels.
There are of course gun games which have 2 players each with 2 analog channels
the virtua striker games support analog sticks which again has 2 players each with 2 analog channels
the baseball games have 2 player with 3 analog channels each (2 for the stick and 1 for the bat control)
driving games have 1 player but with 3 or more analog channels (steering, gas, and brake) some driving games have additional analog controls, for instance Sega rally has an analog ebrake handle. I believe f-zero also has a tilting motion in the steering wheel that would be another analog channel)
flight sim games generally have 1 player with 3 or more analog controls (2 for the flight stick and 1 for the thrust control)
the fishing games usually have 1 player with 3 analog channels, 2x for the reel position and 1 for the reel spin speed.
I can't think of any game off the top of my head that would need more than 6 channels for all players but there are definitely 2 player games that need 3 per player, and 1 player games that need 4 per player.
