I heard much of the players preferred an older version of the game. I don't really know if it really is possible, but I guess adding a version selector to the launcher would get everyone happy about the game. Nostalgists would be happy and so would be those who prefer the game in its current state. This could be the solution to have no complaints about "They removed my favorite content in the game". And also, if possible, a multiplayer support for the older version (but not necessarily via Steam, because I don't think it really is possible). Approximately 90% of the negative reviews on Steam are about the fact you removed the older content. Not everyone like changes, but hey, this could be a thing, don't you think ?
