I'm not going to lie, compared to what I've seen of RDR2, this looks so much more fun and engaging. An open world where every direction can be a new, personal adventure is what I like.
I'm also a big fan of attacking enemy camps and locations, it has always been the best part of a Far Cry games for me. I haven't seen much of that aspect so far but it seems to hint at that kind of gameplay. I also liked Dead Island but ultimately that game was too small, slow, and clunky. I'm liking this footage in comparison.
The only real reservation I have is that 3rd person shooters are hard as hell to get right. That's something we'll probably have to wait for reviewers on.
