One extra observation I would make on top of the sibling's detailed answer is why I believe iRacing is by far the best online racing game. iRacing has an MMR value called iRating which is used to match you against drivers of a similar

What you basically do is take all of the inputs (source files, compiler, exactly what command you're going to run) and then produce a hash of all of that together. Then the result of that becomes the input to the next thing etc. For ca
