Ren'Py does not imply a good game, but RPGMaker does imply certain annoyances. If I see RPGMaker then I know the game will almost definitely have all of the following:
- Limited save system that requires accessing some specific location.
- Dialog system lacking more advanced features. Re-playing scenes is frustrating.
- Most likely going to contain an overworld I have to walk around in with questionable graphics or even if good, still can break immersion. Generally with no path-finding and sometimes without even mouse support.
With Ren'Py
- I can save the game at any time. I can have lots of saves, with screenshots. It's standard and just there, available in same way for every game.
- I can change settings at any time, including middle of dialog. I can also change how quickly text fills into dialog boxes. Not limited to whatever the dev chose.
- Some games support rollback which make exploring dialog trees much more enjoyable. If not, I can still save and re-play any dialog multiple times easily. Including in the middle of dialog.
- Skip option for dialog you've already seen. Makes re-playing with different choices much easier.
- No overworld. Whatever navigation is presented is up to the dev. This can be both good or bad, but it's more often much better than what ends up in most RPGMaker games.
I know some people enjoy the RPGMaker map style, but I suspect the majority is like me and are annoyed by it. It can be used to good effect to enhance the story by animating characters moving around between/during events, but that's done less often and usually isn't good enough to counter all the negatives.
Similarly, some probably like the limited saving style of RPGMaker games too. It can force you to commit to choices, and some like having to do a slower replay to change their options. I think that's better left as an option for someone to self-enforce rather than the engine forcing it.
There's definitely people who enjoy RPGMaker games. However, many of us instead tolerate the RPGMaker aspects of a game because the rest of it is good and in general are less likely to consider them. I've enjoyed RPGMaker games, but it's almost always been
despite the fact it's an RPGMaker game. With Ren'Py, at least the aspects that are going to annoy me are entirely up to the developer.
