Xeshra: Switch is a child console, so obviously no issue there.
Although my sisters children are owning a PS5, so, even a PS5 can be played by children.
Regarding the "quality" of those games, especially this genre which is for me "Retro Style RPG": I currently got 18 of them out of around 600 PC-games stored on my library, this is about 3% of the entire library. Out of those 18 there are 6 "RPG Maker-games", so only one of three is a RPG-Maker engine inside this genre. In total only pretty exactly 1% of the entire library is using this engine.
Despite me being a big RPG gamer and not trying to avoid them. I was even buying several Kagura-games (this is as well a publisher, not a developer... i still call them Kagura-games) i had in mind are pretty solid... despite having such a big "storm" of moaning people who are hating Kagura-games and perhaps are/was boycotting GOG because they was allowing for Kagura-games to be published.
So, i tried hard getting some of the best "Kagura-games" yet... it was only 4 i was putting in my library and 2 more RPG-maker games, so not a big number, yet i feel those are pretty solid games... way better than those "Exe-Create-Kemco games". Still, somehow i feel i would miss something not adding the Kemco-games as well.. at least some good examples of them.
Anyway, there was sometimes some big moaning about many of those games but in the end the "influence" or "contamination" they did was or is rather minor if we look at the whole cookie.
Despite this fact... to me at least... Kagura still seems "blocked" on GOG (so they are not allowed releasing any new titles anymore) and Kemco apparently is still allowed... because either no RPG-Maker games or... perhaps no adult-games... i dunno. The quality itself... in average... is not any better, i would say.
The switch is not a child console sir, there are still a lot of hentai games and otherwise on there. Stuff you won't even find on other platforms. Also, No they are not made with RPG Maker. EXE Create have their own in-house engine that they use for these. Yes Kagura have some good ones but those ARE made in RPG maker. Demons Roots would be one of the best. King Exit just released in English but it became exclusive to DLSIte this time.
