I disagree with this (I used to play Warcraft 3, and currently play Dota 2), but that's beside the point. The Dota 2 OpenAI is only set up for one mirror matchup (impossible in real games) involving one hero on each side, in one lane, and only for the first 10-ish minutes. This is maybe 1% of a real Dota game.

I think you are both correct. Starcraft has a far larger space of verbs at any given moment, and many of them can impact each other, giving it one form of complexity, while Dota2 clearly has a much more complex set of units and abilities, leading to more possibilities total, even if the number of possible actions moment to moment are more limited. But yeah, the bot was a teeny little bit of the game, impressive as it was.
