I don't see any complete story here. Is the author tired of working on the game? Or he got infected with this shitty modern disease “don’t do anything, change the the version number - and voila, release!”?The game had a lot of potential, so this abrupt ending... just doesn't make sense.
I dunno about his "next project" but with a story like that I already doubt him.
I understand where you're coming from, but at the same time, the MC does pretty much become a fully fledged Mage. Yeah, the writing doesn't have a neat satisfying resolution, but at the same time, the sexual content in the game is pretty extensive. In a way, it's thematically appropriate to have the ending be, "Let me see tits out in public" the quest, he's already accomplished everything else, and fucked everyone in the village except (half of) the elderly and minors.
A new game is not just new content, but a chance to try and do content and mechanics in a way that is more interesting. I don't know what their plans are, but who knows, maybe they are ditching the RPGM combat and doing something more like a management game, or they're overhauling the combat with battlefucking? Maybe not, maybe it'll be very similar to the first game, which would also be great, looking forward to seeing what their next project is.
I will say it is unfortunate that there is an entire WIP area that will never get fleshed out, would rather that it had never existed and just have Orcs roaming around unexplained for no reason, but maybe the dev will release the game files and let somebody mod it? Not that it will do much good without the artist, who has a fairly distinct art style.
