It's worth remembering, before attaching phrases such as "wildly successful": This is a game in early access, and with a very important legacy behind it.
What it has sold so far it has sold by virtue of its promises and by virtue of its legacy... NOT by virtue of actually being a good game. Do not mistake one for the other.
It may become the latter, but it isn't there yet, and it has a long, long road to travel before it gets close to that mark.
