Just though we needed a topic here. It's awfully lonely.

I really enjoyed Space Invaders, Centipede, Millipede, Midnight Magic, and Ms Pacman (because the original Pacman was rushed and incomplete it played bad). And Warlords, and Activision Kaboom! with paddle controllers. Do you think the VCS joystick will be twistable for paddle support?

I remember Race/Indy 500 that used the driving controller. It's like a paddle but with infinite spin. Too bad they only released one game that used it (two counting name variants).
Someond also modified the game code from Centipede to use a CX-22/CX-80 trackball. It was pretty sweet. I scored over 100k on trackball Millipede. And that guy from Xbox ported Halo to the 2600. Unreal. Pretty nice game, plays kinda like a cross between Berzerk and Adventure...
