Game Editor hasn't seen an update since 2013, I'd say it's pretty dead
Wave engine isn't open source, and they make you sign up for an account to use it (WHY), and they require you to show their logo on your game's launch screen or they'll sick the wave goonies on you, and they're really slimy about how they describe how the wave engine is free--if it's free then it's free, don't say there's "no payment upfront", what's that supposed to mean? Really bizarre Microsoft-like tactics employed here, and wouldn't you know it the Microsoft logo is on their main page and the language of choice is C#; next thing you know they'll start asking me for a phone number and trying to sign me up for their cloud service. Linux editor is really iffy too, things just don't work for some reason or another. Seems to be some sort of Unity3D clone in all. ECH!!
Personally I'm offput by any engine which only supports the development of a particular type of game. So if I decide I wanna make something that's not a top-down Zelda clone, I gotta go learn something new--or if I decide I want my game to be a little more than a Zelda clone, I gotta figure out how to use the engine for that purpose, which it obviously was never intended to do so it's more hassle than it's worth. I suppose they still count towards being game engines. I don't take RPG Maker games seriously for this very reason, they're always cookie-cutter even with graphical changes--although Yume Nikki is one such exception, but its strengths are obviously not in its gameplay. I feel like Undertale, despite being just what RPG Maker supposedly offers, was developed in Game Maker instead for just this reason: how would you make that battle system in RPG Maker? Sure RPG Maker comes with an RPG battle system, if that's what you want, but sometimes you don't want that, and straying from what the engine offers is painful. While we're on that topic: http://rpgboss.com/ for a FOSS version of RPG Maker.
