I feel like adding prison would add some interest and possibly bring more long-term players to the server. Every prison server I have seen has been somewhat successful and I think that Invaded could thrive with another game mode. idk invaded has just been kinda boring lately and prison could spice it up a bit. Ofc I know the work that would have to be put into implementing such a big addition to the server, but it would be refreshing to know that updates do actually come to the server :/
