It's LESS content in a NEW game, the last of which was released over 10 YEARS ago.
I expected Battlefront 2 with shiny graphics and updated gameplay, not Battlefield with a starwars skin on it.
So, lets go in order here:
1) This is NOT Battlefront 3
Maybe so, but then why call it battlefront? It's an old franchise that has its iconic style already in place. Why take 10 years to make something completely different? That's like finally getting a new Banjo game with minimal platforming (whoops), or portal and making it into a shooter. Nonsense.
2) Battlefront never had a real campaign
Gameplay wise, sure. But following the 501st into the star wars timeline on the clone/imperial side was definitely in touch with the story focus of star wars in general.
3) It's time to forget the Prequels
No, because some of us actually enjoyed them, at least certain parts. Not to mention that the clone wards could have offered amazing fights, what with the vehicles and droid designs.
4) No Space Battles
Space battles were boring? On pc, with 64 players, it was chaotic and amazing, not to mention fairly innovative. It was a concept to be IMPROVED on, not REMOVED for POSSIBLE dlc.
5) Those Graphics are totally believable
It's been said thousands of times and ill say it too. Sure, the graphics are good, but how is the gameplay? are the maps interesting, the weapons balanced, the servers stable? If past DICE games will represent this, then I worry about the quality.
6) No Galactic Conquest
Great mode that EVERYONE wanted in the game. How many game modes will actually be available anyways?
7) Non-Drivable AT-AT's
Minor loss. Those things were undrinkable in the first place anyways.
I <3 Classic Platformers!
Multi-console Owner FTW
plus playing as the CIS was awesome in BF2.
