I found 2 sites with 4 stars out of 5. IGN is one of them. (Delete if repost, thanks!)

Ryse: Son of Rome may be rough around the edges, but I enjoyed the heck out of it. Taking the mighty power of the Xbox One console and focusing it all into one man's blood-drenched quest with his trusty sword and shield is commendable, and I hope dearly to see a more polished, improved sequel.
