I enjoyed Ryse while it lasted, (I got every achievement) but it doesn't last for long. The multiplayer is similar to the Mass Effect 3 multiplayer or Gears Horde mode, so it had a lot of potential. But it fell short with the limited gameplay mechanics. Once my brother and I got all of the achievements, we stopped playing it and haven't been back to it since. I can't say the same for ME3 or Gears.
For those who haven't played it yet, I would wait for a sale on Steam. For $20 or $30, it's a solid value. But anything more is too much in my opinion.
