https://www.reddit.com/r/WildStar/comments/a1yp34/private_server/It's a shame every time an MMO dies. I never once thought about getting back on Wildstar for years but the fact that it's impossible now is kind of upsetting.
In the case of MMOs, private servers are generally your go-to when either the game doesn't exist anymore, or it's in a later expansion. I played WoW's Burning Crusade expansion on a private server for a couple of months in late 2017 and had a good time. It was crawling with bot accounts, but it was something.
