I don't know much about Game Maker, but that looks pretty good

why would ye use game maker for something a this scale? it be such a cluttered 'n shitty engine. This be like using a hammer 'n nails t' bake a cake.

super paper autism

I don't know what Crump be doing with Unity when obviously Game Maker has so much more power.

right now I be making a retro SNES-style top-down action game with Unity

I be doing the same using the id Tech 4 engine. So much power!

YO HO HO! HO HO!, ye can't even mobile/Wii/Wii U/Web Browser export; have fun with yer "powerful" engine, YO HO HO! HO HO!

The joke be ye don't need Unity or id Tech 4 t' make a retro SNES RPG because that be bloated 'n overpowered as hell for that kind a game.

That doesn't hold, then. Unity be being optimized for 2D support, with a complete 2D physics engine 'n everything. Once Unity's 2D tools hit with 4.3, really, what reason would ye have t' develop in Game Maker, (Or other popular 2D engines), especially when most a them don't support console 'n Blackberry deployment?

If it can make 2D games that can run on a potato from the early 2000s then sure. Otherwise it be got unneeded bloat.
