Hello! New player here from a month ago, having a lot of fun. The game was recommended to me by a friend who saw the game on YouTube, and I bought it. However, because of stuff related to the country I was born, buying the game is very expensive and my friend can't buy it. My question is, it's okay to share my account with him? Will I suffer any kind of ban for two people playing from two computers in the same account or is there any other kind of limit? Can we share a self hosted server? Thanks in advance!
