Orlando, WoW from get go was very basic game. They added things as they went, they definitely didn't wait 5 years for release. Logic of "release that will amaze us with its awesomeballs, won't you believe" really sound nice, but it doesn't work that way. It is expensive, incredibly money burning experience. Every manager who have managed big software project will explain that throwing more devs at project really doesn't solve this. Games deflate not because they are not a lot to do, but because what's there to do is not engaging. Games doesn't work that.
IMO Chris Roberts is doing exactly the right thing. Take it's time and develop something really amazing from the ground-up.
Also I wanted to point to you out that he took his time to screw up things in a major, very expensive way.
Making the foundations and making sure that when it releases, it engages the community from the get go and instead of deflating it keeps inflating and spreading to other players (not necessarily core space game players) and leverage from there
Seriously, you have to let that 'game of everything' fantasy die. It has never worked, when someone tried it to work it always ended up badly. Again, games doesn't work like that. It is obvious outsider fantasy. And fact that Chris is outsider to industry shows in full colors. He doesn't even know how to basic space game to work!
