The easiest way to describe Portia is "Chinese knock-off Stardew in 3D". There are plenty of differences, but it's basically a rip-off. The graphics can be quite pretty (apart from the people, who I think are all horrifically ugly). Interactions like combat and mining are clunky but functional. I eventually got suckered in and ended up playing it for a long time. It's good, but it has plenty of balance, QA and mechanical issues. Portia is more focused on building stuff for residents in your workshop than farming, although farming and animal rearing is in the game. It also has yearly festivals, a set of main missions, befriending people with gifts and renovating the town.
