SC2 I'll buy collector's edition to. Just like Diablo 3. I would have bought Collector's for WC2 if they had it at the time.
SC2 collector's will be the first time I buy a collector's edition of any game.
This will be the first physical copy of a PC game I've bought since 2007. I am all about Steam and GOG, so it takes a lot for me to clutter my space with more crap.
