I'd like to see No Man's Sky around that price for the digital version. I bought it at EB at launch and returned it through the game guarantee they offer through their Edge program (I had earlier cancelled my preorder, but thought I could at least give it a shot knowing I was able to return it).
Even in that state, I thought it would be a nice game to have, but not at that price. But now, even at $20, I'm not sure about a physical copy. It feels like a game I'd like to have digitally -- when I feel like playing something but I'm not sure what, it seems like the right kind of game to pop open and tool around in for a while. Much less likely to do that if I have to get up, grab a disc and pop it in.
