Its a fan made very early prototype of a game, handful of races, handful of zones, handful of "content". Its not a game yet and its about 3 years too early for an early access launch, this was done solely for funding.
If 50 random posters on this board made a tech demo using pre-built world building tools and purchased art assets and threw it up on the internet this is the "game" you would get.
That is to say, you could say it was built with love or dedication from people who enjoy playing games like everquest but they really don't know what they are doing tbh.
The term "professional" would not appear anywhere in the vicinity of this, no single person with any experience making video games is involved here.
