RPGMaker is marketed as "the tool for amateurs to make games like professionals."
......well what did you expect would happen when an amateur tries to make a game like a professional without the knowledge required?
it doesn't go well for construction, medicine, electricity or mechanics, .... why would it be any different for games!?
(that's not a problem exclusive to RM tho.... Unreal, Unity, Source, and Java have the same problem: people who mash three files together, slap a price tag on it and call it a day, especially for mobile)
