World of Warcraft players already have an inkling about achievements and the cat's been let out of the bag about the same type of system coming to Diablo 3 and Starcraft 2.

In an interview with MTV Multiplayer, Diablo 3 lead designer Jeff Kaplan said:

When I spoke with lead "World of Warcraft" designer Jeff Kaplan yesterday about the game's new Achievement system, he revealed that eventually players will have a Blizzard Account that shows Achievements from other Blizzard games they've played, including the upcoming titles "Diablo III" and "StarCraft II."

"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."
