Well - all I can say is that it works for me! More seriously, I think that it can be challenging to define the "game" or simulation that a DRL system (or any RL) system depends on. Clearly for things like go the game is preset, for the real world, perhaps less so. People have used it vs physical systems like robot hands though. Also, one of the charms of DRL is the cheating that the agents discover, for example catapulting each other over barriers or blocking doors. But in real world scenarios scams that break the rules of the game (imposed by law or physics) are useless, so you have to rewrite your simulators to remove them, and start again.
