Pretty close to a physical sport, if we assume that most of that code is involved in simulating something resembling physics, or in running simple robot players. Like, how much of a basketball game is concerned with the actual Rules Of Basketball vs. simulating a bunch of people playing basketball? And if you made Space Basketball with characters with superpowers who kept getting balance tweaks as the player community figured out holes in the rules, most of that simulation code would stay the same, as the tiny percentage of rules code evolved.
