KOHCTPYKTOP seemed like building things with transistors should work about the same way, but I've only built things with logic gates (and that, only a little). Could you not actually build circuits the way you do in the game? I've actually been thinking of buying a few thousands of transistors (2N3904) (and resistors as needed, which aren't used in the game) to see how far I could get building a (tiny) computer.

It is close to real CMOS circuits, but idealized -- I don't remember all the idealizations (and I'm really not an expert), but e.g. it'd accept a solution that depends on a race condition working out deterministically.
