Mr.Mumbles: Now the real question for me would be: How do you think it compares to something like 'My Time at Portia'?
They are similar, but there seems to be less content in Staxel. Whole world is unlocked from the start. Fewer quests, no fighting (no monster-based ingredients). Flatter material and crafting progression - one quest seems to have unlocked almost everything except for tool upgrades, rest is only question of money. Big part of the game is creative sandbox - Portia is limited what you can do outside of your farm, staxel allows you to destroy and rebuild anything. To fullfill villager requests you can just stuff all the required components in designated area (I'm trying to build pet shop currently by recycling empty space in their private house), but you could also spend many hours building them something from the grounds up.
Another big thing in Staxel seems to be multiplayer, which I don't intend to touch.
For singleplayer, Portia would win - 200h is hard to beat. If I get half that time out of Staxel it will still be very respectable for the price.
