RPG Maker is a 2D game making application geared toward Role-Playing Games (though other genres have been made). The platform has seen several releases over the span of more than 10 years and has primarily used Ruby as the code core for scripting.
Ranked in these QuestionsQuestion Ranking
Pro Easy to jump into using an intuitive WYSIWYG editor
It's possible to create a game with absolutely no art or coding skills, so even complete beginners can make something.
Pro Large and active community
The engine has seen multiple iterations since 1995, so a large online community exists that is always willing to help each other out.
Pro A cheap license that allows using the software commercially
There are several versions of RPG maker, with MV being the latest and most fully featured: MV ($79.99), VX Ace ($69.99), VX ($59.99) and XP ($24.99), 2003 ($19.99).
Pro MV has HTML5 export
You can now HTML5 export your projects, so you could theoretically host your game on your webserver, and have your friends play the game without ever having to install a single thing.
MV supports HTML5 exports, so it is easier than ever to make your game work on iOS, android, OSX or Windows.
Pro Greater Map layers
MV Mapping uses an additional layer to create better depth.
Con Engine imposes arbitrary limits
Engine imposes arbitrary limits. For example, it only supports resolution up 640x480 in VX ace, and 816x624 in MV.
Con XP and VX are Windows only
The latest version: MV is also available for Mac OSX
Con Conversion to MV difficult
Older iterations of RPG Maker use smaller sprite sizes that require manual conversion to use older RTP assets and older assets are more robust.
Con Inconsistent included visual assets
Included visual assets within MV have inconsistent presentation. Though RPMMV does contain enough to make a small basic title, the visual assets don't often look like they should be mixed on-screen.
