same here. I don't really like 3D art in adult games. I'd never tried SJX if not some user reply on some site. bless them, I'd never find it myself. usually if you search for a well-made adult game, all you see is a lack of gameplay and abhorring 2D- and 3D-art. half of them would be with NTR and rape. 2/3 of them would be with "Futa" brainwashing. SJX is a hidden gem.
anyway, regarding to your topic SJX reminded me of Space Rangers games. they're quite different of course, though they present some similarities in 3D-art design. but mostly it's the vibe. any adult Russian know these games, even if not familiar with space sims and quests. but the atmosphere of a frivolous, funny adventure is here in SJX. as well as some freedom of actions.
