BTW if you want to collaborate together to spec out the game we want maybe someone who already understands the relevant theory can help create such a game.

I want to start with questions like:

- create a voltage divider to do ___

- what value of resistor is needed to bias the transistor properly to start oscillation? (would show the rest of the context)

- choose three components to create a low pass filter

- which transistor would work with this oscillator circuit? (multiple choice)

- why doesn't the LED in this circuit light?

There are thousands of simple questions/exercises that would (I think) pave the way for slightly more complex questions... it would be such a fun game :)
