When talking about RPG creation software, if a game creator is "flexible", you're going have to code a lot to make a halfway decent game. It's pretty much a euphemism.

Typically, "flexible" RPG creators usually come with crappy default systems, encouraging you to code your own. It sounds easy until it turns out the software doesn't even come with any commands to gain access to the software's enemies and items, meaning you'd have to code THEM too. It's almost the same as coding your own game from scratch.
A good example of "flexible" RPG creation software is RPG Toolkit.
