Basically Dark Horse Comics took the original draft George Lucas created way back in 1974 and is doing an 8 issue miniseries adapting it in comic book form. So its one alternative take or "universe" of existing canon. They're also drawing alot of inspiration from Ralph McQuarrie' art.
Normally I don't collect Expanded Universe stuff. But this is the fiirst time I've seen them do alternate universe stuff. And what I like most about them is that they have the classic feel while doing new stories (something I never got with the prequels). Also, like KOTOR, it feels like anything can happen in this new universe.
Here's some samples:
Left - Annikin Starkiller, Middle - Kane Starkiller (Annikin's father), Right - Deak Starkiller (Annikin's brother)
