Divinity: Original Sin 2 is a big, beefy game. It's also one that you can, if you are so inclined, play from start to finish in not much more than a half-hour. And if you don't believe me (which would be an entirely reasonable position to take), then watch this video of a guy named Onin actually making it happen. 

This is probably the worst possible way to play an RPG but it's also very typical for speedrunning, as Onin takes advantages of exploits and his obvious familiarity with the game to get through it very quickly. At around the six-minute mark, for instance, he goes after a group of large crocodiles, but only attacks the one that's carrying a particular pair of gloves he needs. He uses invisibility and manages his action points so he can kill and loot the required croc in a single turn, after which he plays dead to end the combat sequence (he's playing as Fane) and then uses the waypoint system to zap back to Fort Joy.
