I considder Realcrafter to be a pure Hobby Architecture.
But if the person making a MMO Game is also just a "small" hobby programmer,
this might be excacly what he wants. - To simply create a working gameworld
to express some ideas. Its not that most of the Hobby developers really want a big
MMO Game. They eventually swith to other sollutions later.
What counts is the fun and experience to get a MMO Game running at all.
Taking a "serious" start to MMO, it ist probably not the right sollution.
With a "better game", I mean that a running! game made with a "Maker" is better than a not running game
made with a complex Architecture.
