I’m not sure if you missed the post later in that thread where Umborls explained what the comment about official servers really meant, but I’ll reproduce the explanation here:
In other words, official servers are meant to be the “real game”, in the sense that they are how the devs imagine playing the game. They’re not just the “tutorial/noob zone”, they’re what devs envision and optimize for. Everyone is free to tweak and change the game as much as possible on their own servers, in single-player, or in co-op, with or without the help of mods, with or without their own admin rules.
The devs recognize that the number of private servers outstrips the number of official servers by a large margin, but that doesn’t change the purpose of the official servers, which is to experience the multiplayer aspect of the game the way devs envision it.
Again, let’s quote the “shift to private servers” bit here and look at it:
On its face, it almost sounds like they want to get rid of official servers and have people go to private servers, right? But that completely ignores the whole context given in the “why?” section. I’m not going to reproduce that section in its entirety, but here’s what I consider to be the salient part:
That completely changes the meaning of the “shift to private servers” part, doesn’t it? Basically, it says “Many people don’t like our official servers and migrate to privates, which leaves the official servers underpopulated, and playing on a server with only a couple other players is not how we envision the game should be played.”
If anything, that bit confirms that the official servers aren’t a tutorial/noob zone, and are supposed to represent the devs’ vision of this game.
So why do they expect the “shift to private servers” to continue? I can think of a couple of explanations. The more idealistic one is that they understand that mods and settings provide a myriad of ways to play this game, and it’s quite natural that players will seek their own niche in that variety. The more jaded one is that they know official servers just can’t handle the game, due to performance problems and insufficient moderation capacity.
None of that changes the fact that the official servers are the “real game”, however unloved that experience might end up being.
No more than Minecraft or Terraria.
