I'm still waiting for fully linuxable grasscutter without hassle as well as main story completion.
edit: on their site cultivation is listed as having linux build so I guess gc no hassle is already available.
double edit: I tried setting up cultivation on steam deck/bazzite and it would insta crash seemingnly when trying to download the grasscutter files. There is a fork that seems to be more up to date but it doesnt have linux releases past some old verasion.
Grasscutter is an unofficial reimplantation of the game server that you can self-host. It allows you to do many things that are usually reserved only for devs like spawning monsters, getting characters via one command, getting artifacts with the stats you want etc.
Cultivation is a launcher that allows you to easily run that server and make game connect to that server instead official ones.
