The GameMaker engine series is going free for commercial use on PC

Off topic, but I was surprised to see a game I enjoy Synthetik update to latest GameMaker. It impressed me that the game was built around some engine like this; I wouldn't have guessed. It was also surprising seeing a going on 10 year old game with a sequel already out get an engine upgrade! https://store.steampowered.com/app/528230/SYNTHETIK_Legion_R...
