I have to credit Penny-Arcade for pointing this out today. It’s some games made by GameLoft that are basically clones of Blizzard’s games, but they’re built for mobile devices. Of course, all of this is legal — they aren’t using any of Blizzard’s source code, artwork, or product names. (And people say copyright is too restrictive and is strangling creativity. Heh, heh.)
See how quickly you can figure out what Blizzard games they’re cloning. It shouldn’t take too long.
