I've been following this community [0] which has unofficially relaunched a Korean online game which originally only lasted from 2003 to 2007 [1] and I played when I was a kid. It's amazing to be able to login into the same UI/UX and play the same game almost 15 years later.
Does anybody have some resources on running your own custom servers? For example, how private WoW servers work, were they reverse engineering?
