Because the "and more" is trash that isn't worth it?
Space battles got boring incredibly fast.
The new clone voices were terrible (which is completely inexcusable because they had temura morrison voice act the campaign voiceover).
Heroes were poorly executed.
Hero assault was loving stuff.
Almost none of the new gamemodes were any good (hunt was ALWAYS one-sided)
The good maps from the first game were removed (rhen var harbor and citadel, tatooine dune sea, bespin platforms).
The AI was not improved at all.
The new unique units were rubbish.
Faction variety (like pilot units having different weapons on each faction, droid and rebel snipers having two zoom levels) was canned.
Battlefield is just another generic console shooter without mods to set it apart from other games. To me, the un-moddable frostbite engine is just another excuse to reduce shelf life of games so that they can pump out more titles and sell more dlcs.
I swear if the new game has a campaign and its your typical rebel-sided snorefest I'm going to flip a table. The only point I'll give Battlefront 2 was the fact that it had a campaign that was pretty damn decent and not just "play all these instant action levels". AI still sucked dong though.
