Even Ubi's first effort this gen, AC Unity, is breathtaking.
AC Unity's sandbox has stunning authenticity and detail to everything, from the architecture to the highly lifelike npcs. Awesome game so early this gen.
Not that noobs here would know, of course. But moving on.
AC Syndicate, Origins and Odyssey, along with host of many other games, continued this incredible trend.
Each Ubi game world has great atmosphere, stunning eye for detail, and awesomely lifelike societies on npcs going on with their daily lives. Not to forget the incredible weather effects.
I've played pretty much every game on this gen, on PS4, and I gotta say there are few that can match the mastery of Ubi when it comes to creating believeable virtual worlds. Bethesda fell far off the mark with their F4, for example. And Rockstar, with RDR2, just showed they are still stuck on last gen and are no match for the superior Ubisoft. No match at all.
So. Ubisoft is the king of virtual worlds this gen. Fact. Only fools and clueless noobs would argue this. Fact.
