An interview with World of Warcraft lead designer Jeff Kaplan on MTV Multiplayer from the other day (thanks Mike Martinez and Joystiq) reveals that Blizzard plans on implementing achievements into many games, including Diablo III and StarCraft II, which is not that surprising considering plans for WoW achievements have already been unveiled (story). These achievements will be tied to what are described as "new Blizzard accounts," which will lead to players having a "Blizzard Level." Word is:

“Eventually, our plans are for the Achievement system to become an account-based system,” he explained.

When the new Blizzard Accounts are active, a player’s ‘WoW’ points can be added to an overall score dubbed an account holder’s “Blizzard Level.” “It’s basically a gamerscore,” Kaplan said, when I made reference to Xbox Live’s Achievement system. “For now the points are just a ‘WoW’ character score. As we graduate to that Blizzard Account system, which is right on the horizon, it will switch over to a Blizzard Level.”

He added, “Your ‘WoW’ score would be just one factor that will go into your Blizzard Level. And rather than call it a ’score,’ we just wanted it to be like you’re leveling up on Blizzard games… You’ll have this Blizzard identity, and you’ll be able to see things like ‘Oh, this guy was great at Diablo III, but he never played Starcraft and he was mediocre in WoW.’ That sort of thing.”
