I played solo, on Savas(small overcrowded map) and it was very difficult, but after consecutive hardships, I got a good house and even worked my way up to crafting guns. It was pretty fun but it took an overwhelming amount of time and frustration, I have never played a game more stressful.
I wouldnt recommend if you are employed.
I wouldnt recommend if you get mad easily.
I wouldnt recommend if you have no friends to play with.
