GameMaker is a 2D game engine used by a number of highly rated indie games like Undertale, Hyper Light Drifter, Katana Zero, and Risk of Rain. RPGMaker is a piece of software that lets you make top-down JRPGs generally in the style of the 2D Final Fantasy games. Because it takes that opinionated approach it's widely considered very easy to use. You're not fiddling with e.g. a physics engine when you know what genre and style of play you're doing doesn't need it. Likewise RenPy is designed to make it simple to build Visual Novel style games, and as the name implies it uses Python, so between using an easy, popular high level language and taking an opinionated approach tailored to one genre/playstyle, it's a highly productive and approachable engine for newcomers and indie devs with limited time.
