It doesn't have to have any or all of the games of the current one.
I'd like to do one game, but make it a better one, hence the original driving game idea.
Tetris, I already wrote for my 144 LED matrix, so it's a bit too easy.

Breakout, I like the idea of a pot for the control, there was a breakout arcade machine with a knob,
but I need trigonometry that I have not yet solved in PBP (ball bouncing off walls at inverted angles).
