I disagree 100% on wanting a new Battlefront... In today's gaming world, where MP is an arena already heavily dominated, and filled with failed attempts to dethrone, I think any SW game needs solid SP gameplay in it to succeed. The rich Star Wars universe, with diverse characters, worlds, and a detailed history, is what would make this hypothetical game what it is, IMO. Story has almost always been where SW gaming has seen great success.
Battlefront was a clusterFUBAR as far as story went though... It was pure MP. Unless this game revolutionized FPS MP gaming, I think it would be a dismal failure for them to even attempt to jump into that already crowded ring where there's so many failures, and the winners are long-established. Could a SW FPS game ever compete with a COD, or Battlefield? Or maybe more similar, a HALO type game?
BioShock had story. GoW has story. HALO and COD even have involved backstory and solid SP campaigns. Battlefront, to me, would be destroyed if it came out today with updated graphics/gameplay as its only changes. I'd say what they need more of is Dark Forces/Jedi Knight/Mysteries of the Sith, or Republic Commando (with MP). They're up against competition now they've never really seen in the past with their FPS games though. Battlefront is like Battlefield, and I just don't see Star Wars winning with that model anymore.
And Force Commander is still the most underrated SW game in history. My computer can even run it well now.
