Hey come on guys, I'd really love to by the Warcraft battle pack from you guys, but it makes absolutely NO sense for ME to do that, because I still have my original codes registered on battle.net, and I can just download them from there. I would LIKE to support your effort, but it would be silly for me to do so.

You guys NEVER have a discount over 20% on Warcraft. What's the deal? Can you guys do some sort of code sharing thing with blizzard so I can just grab your package here? Could I get some sort of code somehow to get it?

It's only $17, after the current 15% discount.

Warcraft 2 can be downloaded from Bliczzard’s site? I know that they still support classic Starcraft and Warcraft 3 installers, but I thought that W2 is not available in digital form beside GoG.

You're correct. World of Warcraft and Warcraft 3 are available from Blizzard; Warcraft I and II are *only* available from GOG.

Honestly, OP, the GOG sale is not for people like you -- that is, if you already have the games, other retailers aren't going to try to get you to buy the exact same games again. The sale is for people who do not have a copy compatible with modern hardware...and, honestly, $15 US dollars ($12 while on sale) is a steal when eBay and other sites are charging at least 3 times as much for antiquated disc versions which don't run on modern hardware.
