(Hello! So I couldn't help but notice that most exported games are for two systems. How do you do that?)
Depends on the game engine that you're using. Also, I don't think it's necessary to make more than one build. Browser build is probably the best thing you can do accessibility-wise but Windows build should cover most of the users.
(Okay, cool. I'm using RPG Maker MV. I use a Mac primarily, so I like to have the option, but I can do a Windows-only export.)
Doesn't RPG Maker MV have a Mac export option? I was pretty sure it does....
(Yeah, but I was just curious on how to fit both into one download.)
