How in the world this got an E for everyone rating is beyond me ($$$$). Most of the gameplay is innocent enough, but once the plot gets rolling you really have A LOT of material not suited for young children, and they are major plot points so you can't really skip past it.
I'm not really one of those up on a soapbox about social issues, and I'm trying to not give too much away, but there is are major plot points about suicide, racial displacement, and racial genocide.
While entertaining and fun at times (still think the ring combat was beyond stupid), this thing should have definitely had at least Teen rating.
And the plot itself, at least for older gamers, terribly predictable. You could see where they lifted their inspiration from at nearly every turn, the only semi-original thing in the game was the most annoying part of it.
