But like, give for example rpgm games, atleast you can walk around [...]
So, one of the reason why you like RPG Maker games is the main reason why people tend to dislike it...
Note that this isn't a criticism, just a observation, and also a demonstration that the engine by itself isn't really to blame. Like for any other game engine, the problem is what people do with it, and what players expect from it.
While the realization isn't as good as it should/could and, from my point of view, the interest relatively limited, what a game like
Lust Hunter have in common with the usual Ren'Py games, except precisely to be made with Ren'Py ? There's also the good old
Sakura Dungeon, among some other games who decided to not follow the VN route.
If you want to find interesting Ren'Py games, you generally need to looks at games less liked. Precisely because they don't appeal to VN lover, while members who prefer more gameplay tend to avoid Ren'Py games, and therefore don't found the ones that could
possibly interest them.
