I had to do some research to see if the original Battlefront games even had a campaign.....
They were just a bunch of missions tied together, with some clips from the movies as cutscenes. The original games didn't really have campaigns.
As long as there is some kind of single player mode (which there is) I'm happy. Better than what Titanfall and Destiny offered (which was nothing).
I do hope there is a Galactic Conquest mode, though. That's the only aspect of single player from the original games that was even remotely memorable. Generally, I just enjoyed engaging in Instant Action skirmishes against the CPU myself.
And hell, upon re-reading the news, it sounds like we'll be getting special content for single player/co-op. The original game just used the mutliplayer maps for the single player missions. So this could actually be even more than what the originals offered.
