I played ep 1 of A New Frontier and you can definitely tell they made it a lot more console friendly. Which in turn makes it easier on PC as well. Bashing/stabbing walker heads is now just an action button press. Its Q and E on PC so I'll assume it was Square and X on PS4 where you mashed one and pressed the other when you filled the meter... but for melee prompts they swap it up between the two, and sometimes the left/right/up/down will be melee... but when that happens its during intense scenes as if you would have dodged anyways. So they don't mix it up too much. I even had a shooting sequence that was in classic form but much easier.... basically the super wobbly head motion paired with the shaky cursor is gone... that was pretty annoying even with a mouse.
The game looks a lot sharper than the first. The dialog was much improved when searching too.. it feels a bit more natural when you interact with items that you can't use. I mean that wasn't really a knock on the first game, and it didn't really need an improvement. But its interesting how they made it feel more realistic rather than a normal sigh or headshake and a "busted" or "we wont be able to use that" line.
The choices you made in season two seem to affect flashbacks rather than this story. You can use your save data Mass Effect style, Start fresh, or even use your save data and change choices you made. I assume you can pick and choose, but I went ahead and stuck with my decisions... I don't like to take back, even if I regret my choices... that's what I love about continuity games.
