Well, I wholeheartedly approve of achievements in Diablo 3 and Starcraft 2 (and don't care one way or another about WoW), but when I first read this, the idea of accounts made me a little nervous, as it would probably be fairly easy to apply billing to it, or something. But, considering Blizzard has offered free Bnet for
years, I think they can be trusted to offer a great service. So, yeah, it sounds pretty cool.
I was thinking it would be awesome if they patched Diablo 2, or Warcraft 3, or Starcraft 1, or some combination thereof, to support achievements as well, and made these Blizzard Accounts function for all Blizzard games. I doubt this will
happen, but I just thought I'd mention that I think it would be freaking
awesome.
And, you know, who knows...it
could happen, Blizzard is really great with their long-term game support, after all. Diablo 2 and Warcraft 3 got patches recently, and I don't know about Starcraft. These Blizzard Accounts sound like an interesting idea.
