Jeff "Tigole" Kaplan must have finished his work on the expansion because he's talking a lot lately -- first he's all over the forums giving us tidbits about what's up with Wrath, and now he's had a chat with MTV Multiplayer about what Blizzard's planning to do the same and differently with their achievements system.
He openly acknowledges the impact of the Xbox 360 and Steam platform's achievements systems, and says that Blizzard even found themselves calling the rewards "achievements," just because the idea was so well established. But they're trying to do things differently as well: whenever they can they'll offer a progress bar, and give players access to many of the stats they have, so it'll be easy to track just where you're at in the process of earning the points.
Kaplan also says that the UI team is working on completely opening up the system to mods as well, so expect to see some wild achievement addons when the mod community gets their hands on it. We do still have one more question, though: just what kinds of rewards will all these achievement points be used for? Kaplan, if you're still up for talking, feel free to chat with us.
