This game looks awesome. But the controls were very poor, often no responding the way you intended. Very short title. They intend for you to play through more than once, but what's the point? Definitely a game worth renting, but I don't recommend a $60 purchase for 5 hours of gameplay.
I had completely forgot about this game when I finally got my xbox one. I rented it, and after an hour of play went out and bought it. WIth all games, things will get repetitive. If that bothers you, then you might not like the content as much as I do. I won't touch details of the story since you can read all about it, but I enjoyed it. I think the game mechanics are amazing. Reminds me of the fighting in Sleeping dogs. With good timing, you're a monster, and one bad misstep and you can be done.
Online play is much like the regular game, so if you enjoyed the story you'll enjoy the arena and such. Shelf life is about 6 months depending on how fast they bring out new content hence the 9 rating. They would need to add a lot of content relatively cheap ( season pass may be worth it), but I can't judge the future. Please Rent this game!
