RPG Maker 2000 ranged from incredibly simple to incredibly complicated. Making a full scale RPG of decent quality could take months (I wouldn't know since I never finished one). In order to make even basic cutscenes, you had to mess with switches and variables until you had pages of script. It had one pre-made level, a rather mediocre RPG courtesy of Don Miguel. Little Big Planet has 50 pre-made levels. But it was pretty popular and not many people would doubt its quality. And don't even get me started on getting new content for RPG Maker. You were held hostage to crappy sharing sites.
Why are you bringing up RPG Maker? That is like telling someone who isn't fond of Algerbra that Calculus is really hard.
