Without 24/7 Danzig, the only difference in RO1 server browser is instead of there being 1 Danzig server full of people there would be 0 Danzig servers full of people.
24/7 Danzig didnt kill the game, it kept it alive longer.
And if Apartments wasn't made by Tripwire we would have gotten some hideous remake the moment the SDK comes out from someone.
It's virtually impossible to prove or guess based on speculation, but if one did a survey, I wonder how many players would say they join a server based on how many people are playing not counting bots? I usually don't really look at the map before I join a game. Instead, I'll usually look at the ping and total player count.
What disturbs me is that there's indeed a point - if everyones playing only one or two servers out of the many others (again, not counting bots) with the only other server being Danzig 24/7, how many of these people are absolutely in love with Danzig versus how many just love the mechanics of RO and just want to play on a stable server lacking bots?
Again, I'm only speculating. It's impossible for me to tell. I can say that a friend and I have filled usually empty servers up in the past simply by being there and playing against one another and one by one, we saw more and more people. That same server stayed full for about a week before it "died" again. Granted, this was on an entirely different game, but I do wonder if it's more about how many people are playing.
