Starbound is the closest similar reference I can make to No Man's Sky, excluding the home and base building aspects.
Starbound has the same concept in it's gameplay loop. You are stuck on a planet, you need to upgrade your ship (get a hyperdrive), explore the planet you start on and gather stuff, make things out of this stuff to be able to travel to harder / more difficult planets that contain higher level / more valuable resources than the last one.
Were people confused about the Gameplay Loop of Starbound, Where people confused about the gameplay loop of Minecraft? Why is there an exception to No Man's Sky.
Do you not see how ridiculous this is.
Bingo. There are plenty of open-world/mmo/sandbox games out there. If it's good, it's good, if it isn't it isn't.
I really hope Starbound goes 1.0. I haven't played it in over a year, but what I did play of the beta was awesome, I'm really looking forward to the completed game.
Positive reception already exists from the folks that actually played a preview build of the game a few months ago. The same doesn't apply for Mn9.
I don't even know what kind of comparison you are trying to derive from using Mn9 as example. Especially considering it's completely unrelated game, from an entirely different genre, nevermind completely different studio no less.
Are we now running out of examples that we have to refer to failings of other unrelated games, as some sort of confirmation that the same applies to No Man's Sky?
That's the problem with these previews, they're very limited. Previews of Evolve were awesome, but that game proved to have very little magic outside its first few hours.
I've just been playing The Division, and that game really dives off a cliff after you reach level max. Up until that point it was amazing though.
Then you have a game like Skyrim, which I had no problems putting 100 hours into and practically making my own content by exploring, crafting, managing houses, etc.
We still have no idea if NMS will provide a day, a month, or even years of play value. And there's no real formula for figuring out how to make a game feel as fresh in hour 100 as hour 10. They just have to release it and see if it sticks.
