The game is actually only $49.99, but if you want the galaxy edition which has a pile of extras, it's $79.99, so other than the extras, the game is the same (as far as I know).
I did buy the game, but am waiting to make sure it's good before I open it up and install it
From what I see here and other places, it seems like a worthwhile game, so I'll probably rip it open and get it going.
