Got to play for about 20 minutes while at work, here's my quick analysis after playing through two games:
I don't know why, but after the old movies and all of the old games being either ancient or more cartoony, a la Star Wars: The Old republic, this game needed to be done. It needed to be done and presented in the way that it has, because it is fucking gorgeous. It's classic Star Wars presented in such a modern light and take that you can't help but marvel at it. Really incredibly well done.
I enjoy the partner system very much. It's nice to have a target to follow around if you're still new and shoot where they shoot.
The sound design on the game is phenomenal, as well. All of the sounds are very very familiar, but when they're close-by or you're the source of the sound (such as the classic Stormtrooper's rifle shot), there's a lot more bass and "oomph" to it, to give each shot power.
The gameplay feels very smooth, and they've done a good job of helping to capture some of that old Battlefront feel, especially in the death cam. That always seems like such a minor thing, but my first death gave me instant flashbacks to Battlefront 2. I think, thus far, they've done a good job of making you feel like a grunt, like previous battlefronts, but also making you feel capable with really tight gunplay.
Speaking of, the gunplay feels rock solid. The grenades might throw a little wonky, in my opinion, but the actual act of moving your weapon and firing is great. I think this is one of the weaknesses that the previous Battlefronts had that I'm glad DICE shored up. With so many modern shooters out there, I think it was important that they did it well.
BE WARNED: Shots take time to travel, instead of hitscan. You'll likely need to lead a bit.
I haven't played enough to comment on the lack of a class system that's instead been replaced by a loadout, but thus far? I'm honestly not too broken up about that aspect of it. The rest feels like modern Battlefront, in my opinion.
