Created by Yo Yo Games, GameMaker was used to create games such as Hyper Light Drifter, Risk of Rain and Nuclear Throne. Conversely, MonoGame is the backbone of games like TowerFall: Ascension, Mercenary Kings and Transistor. One GameMaker-developed game is Savant Ascent, which Yo Yo Games named as its favorite game of 2013 for the development platform. The stylistic shooter was announced for PS4 this morning following its debut on PC, Mac, iOS and Android in December.
