I really like this game. I haven't had an RPG before, and honestly wasn't really aware what that meant until I bought the game. But I am actually really enjoying it. I've already finished it once and am determined to replay to get all the PS4 trophies (though I finished it first with help from walkthroughs because knowing my choices could change the fate of even a companion stressed me out some). The first things that appealed to me were that it was a third-person game that didn't have a turn-based combat system. I'm really into Assassin's Creed, and from the gameplay images and cover, this seemed to have a similar design. I love the story, though, again, the fact that there are different endings is something new to me for a console game. But all in all, love it. I've gotten attached to the companion characters, and will probably keep replaying it in the future if for no other reason than to hear them talk to "me".
Also, soundtrack is pretty good in my opinion. I like how the music changes depending on what's around you (monsters, humans, plain wildlife, etc.) The fact that certain items have weight and that there's a limit to how much your character can carry almost worried me, but when I realized that it only affected whether or not I can sprint, and that it may increase depending on your level, not so bad.
