It's often said yeah, but this year's first 3 months having been stronger than all of last year, so there's some merit to it right now. That's not difficult though, considering how mediocre 2016 was.
It is good to appreciate what we have right now though, rather than constantly assume everything we see in (what might be extremely scripted) promotional material will be better than (or even as good as) what we have now. This looks great and all, it really does, but we have yet to see anything from Shadow of War outside of this well edited 15 minute demo. Hitman 2016 is fantastic, Horizon Zero Dawn is amazing, you don't always need to have the next thing.
This is what I want from games though, systems which allow players to forge their own stories through their own actions. I'll be curious to see if it all plays out as well as it did in this demo.
Also, what's going on with the fighting? Is everything aside from bosses one hit kills now? And is it open world anymore, or just bases?
