Gran Ende III is a decently challenging combat RPG. And a sandbox rape/abuse/corruption simulator.
It's somehow two different games at once and this is my major complaint about this game. The main quest & gameplay loops can be finished without seeing anything lewd, and conversely, anything lewd that happens has 0 impact on the story or the characters.
Well, maybe there's something at the end which somehow makes all the sexual abuse meaningful to the story, I honestly don't know because I stopped playing out of boredom after 5-6 cleared areas. But I doubt it.
Separating the main story from anything sexual is a huge mistake when designing a lewd game. I would compare this to playing a Zelda game and then looking up some lewd Zelda art in between missions - or after you've finished the game. There's really no point to this and it destroys all immersion.
The game in itself isn't interesting enough to finish without the lewd parts, even though it's decently written and actually balanced pretty well. It's still your bog standard RPGM and you've all seen it a thousand times by now if you've spent any amount of time at all here on f95zone.
Regarding the lewd parts; I must say it kinda destroys the point of abuse/rape when the characters must actively choose to go and get abused with plenty of warnings beforehand. Warnings along the line of "I will probably get raped if I go through this door" appear frequently. And anything lewd only happens during the "night" portions of the game. It feels very structured and volontary. I feel really dumb when choosing to go out to get repeatedly abused at night time, because you can, you know, just not do that. Because why would anyone? The lewds just feel like fan service without any point.
The lewd scenes and art uses a lot of repeating assets, and there's no indication of when you've reached the end of a lewd "story arc". This means you'll be watching a lot of repeated lenghty scenes clicking through "oh oh oh, ah ah ah"-type dialogue. It gets really boring after a while.
If you're here for lewds, or a story filled with lewd elements, look elsewhere. If you like RPGM games with no sexual content then I guess this game is for you. But honestly who would play an RPGM game without any lewds in them? You'd be better off grabbing a super nintendo and playing some Zelda or Secret of mana or any other retro RPG without sexual content.
