Been playing it the past 2 days, not too far in, on my 3rd planet with a decent number of upgrades unlocked.
I'm enjoying it, though I don't really like the Dark Souls-esque combat system too much. The controls are bit clunky on the PS4, with a lot of wobble when you try and aim him in certain directions. The dialogue is fine, and the supporting cast are enjoyable, with BD-1 being a very fun companion to prowl around with.
The sliding mechanics, can just *bleep* right off though. Seriously, they love sliding sequences WAY too much in that game. The sliding stuff, coupled with drops to your death, coupled with the above mentioned wobbly controls when trying to direct Cal is very frustrating.
Overall though, I'm enjoying it so far. Though it makes me want to play Force Unleashed though, the Force and combat just felt way more polished in those 2 games than this one. Though to be fair, they are going for more of a minimalist combat system, so it's hardly a flaw, so much as just a stylistic choice that I don't enjoy as much.
