Just played a few games on the PS4. Couple thoughts.
Graphics are outstanding. Really impressive. Runs very smooth as well. Great skyboxes and the explosions looks awesome.
I didn't care much for the 16 player mode, got bored of that pretty fast. The larger scale AT-AT mode was pretty fun, though. Cracked up a few times when new players flew X-Wings and Tie Fighters into mountains.
Not sure if this'll be worth purchasing, but it's fun, and yeah it definitely doesn't feel like Battlefield, besides maybe the scale of the battles. Feels kinda like an old school FPS.
