Just as StarCraft hit the top of the sales charts after StarCraft II was announced... Diablo II has jumped to #1 on the PC game sales chart at Amazon.com following the announcement of Diablo III. It's also #18 across all platforms. Yikes!
I re-installed Diablo II last night. Have you?
What's more interesting is that every Blizzard game starting with StarCraft is in the Top 20 on Amazon's PC sales chart.
