Wow, what a great game. It had a few technical issues. Floating objects a few times, some frame rate issues when it would auto-save, but aside from that, it's amazingly impressive.
I don't want to give any spoilers, so I won't. I will only say this. If R2 has on this game is scale, then R2 has nothing. This game has amazing scale.
I won't go any further into it then that.
I am going to start playing R2 now, and tell you all what I think about each in comparison.
