Correct, it's called Star Wars Battlefront, which is pretty much the front line of a battlefield, or, as in the dictionary:
'Battlefront (noun): The area where opponents meet or clash. / The line or sector in which armed forces engage in combat.'
Yes, I agree with you, the game would be better with space battles. Just saying the argument that it's not called Star Wars Battlefield is invalid.
That being said, I do hope they add mod support so that some modder can add space battles. Heck, I'd even pay for Space Battle DLC!
