I wasn't being sarcastic, I've seen plenty of games made in RPG Maker and many of these games released as freeware actually look better visually. I haven't kept up with newer releases of RPG Maker so I assumed they just improved it to add those newer features, soon afterwards I learned that it was a new custom engine.
As for Windows-only;
As another point, I don't get some of these pledge offerings. I'm more surprised people have paid for these.
You have to pay $750 to help work on the game for them? If your sidequest isn't good, will it still be included in the game?Pledge $750 or more
THE DEVELOPER ============================= Create your own sidequest within Elysian Shadows with your area, map, or house, and your item, NPC, or enemy ● Signed concept piece for proof of authenticity ● Optional invitation to come crash on our couch for a few days and help us realize your creative vision.
Pay $500 to sleep on their couch?Pledge $500 or more
THE EXPERIENCE ============================= Come crash on our couch for a few nights and experience the authentic life of indie game development, complete with drinking coffee out of mason jars, participating in software discussions, complaining that our artists' assets don't work in the toolkit, and finding all kinds of bugs for us. ● You can also guest star in a Chapter of "Adventures in Game Development," and even promote your own gamedev project!
There's several more pledge levels like this, to pay them to work on their game. To pay them to beta test and look for bugs. Usually this is done for free, asking for volunteers. Or kept within a tight group to keep stuff from potentially being leaked before release.
Plus they want to make each platform release unique to their respective platforms with different content between them, yet they also want to make the save files swappable between them. Would this even be possible?
