So my friend is a Star Wars fan and got "banned" from this subreddit...He told me to post this on his behalf... KEEP IN MIND I HAVE NO CLUE ABOUT ANYTHING REGARDING STAR WARS
This is what he said:
Maps are more than 8, they just have not given details on it. Also the maps from the other game went from the classic and prequel, this is used to be a intro to the sequel trilogy. Also each DLC map pack consists of 5-6 extra maps confirmed. Lower player count for balance and map design, its like putting 64 people on metro, it doesn't work out so it makes sense to lower player count. Also with less people on server it enhances performance and fun on the game. There was no "campaign" in battlefront 2 as it was just normal multiplayer games with cut scenes and objectives.
Literally no difference between the map in single player vs multiplayer. The campaign in Battlefront is going to me more in depth that the prior one. Galactic conquest was a game mode that most people did not play. Instant action is in the game but they said "Modified to fit the new game, but stuck to the fundamental features. Changed the load out system to make it like bf4 and cod where you create a class as compared to selecting pre set classes, don't see how anything went missing.
