When I bought SC2 at retail, I took the box home and found that it contained not one copy of SC2, but two!
Larger version on TwitpicThat was awesome, because I had deliberately waited for the digital distribution release to buy SC2, which meant I had to wait an extra 15 hours after launch for it.
I suffered through having to use Blizzard's abysmal "downloader"; it took me three nights to download it and it even failed and had to be restarted at one point. Then, I stayed up till 3AM to actually buy it, only to find they wanted me to pay $90 for the privilege when JBs was selling it for $69 (get stuffed!).
I was pissed, and bought it from JBs the next day. Lucky I did, because I got two discs (and CD keys) in the box and sold one to my cousin, which meant I actually paid $35 for SC2. Take that Bobby "Money-Bags" Kotick. FYI, you're doing digital distribution wrong, arsehole. Go look at how Steam does it and just copy that. In fact, just throw in the damn towel and put SC2 on Steam.
