What do you mean by token costs? Does it cost more tokens to support an older graphics API than a newer one?

Yes, because it would not be an "or" but an "and", more features = more tokens.

		It's not an "and". GL 2.1 has all the features necessary for PS2 games and is still supported on modern systems. Older APIs may be slightly more verbose than newer APIs but that shouldn't matter to an AI.
