People just need to judge it on its own merits.
Is it a terrible game? No, not in my opinion. Is it a great or even a good game? Absolutely not. Is it the epitome of mediocre? Very, very mediocre after having played it (free copy from Ubi). The issues I bulleted in my previous post jumped out immediately. They're all very, very, veeeeeery prevalent. And that's kinda a shame. Ubisoft obviously spent a lot of time building this absolutely stunning world. I mean if you haven't taken the time to just sit/stand there and look at it, you're missing out. Really. The vistas in this game are truly a sight to behold, especially as alternating weather rolls in. Just f%#&ing wow.
Still, its a shame that the gameplay is so hollow and so disjointed from said world. While yes, it can be a great deal of fun in COOP and that is where it really shines IMHO, it doesn't negate the fact that it just isn't a good game. It's just, like ya know, kinda there? It's that game you know you should uninstall because it isn't good but just can't quite do it. You just kinda know one of your mates has it, and he'll want to do a raid or something and you'll wanna do it as well because nothing else like it exists? That's kinda how I feel about it, and that's the sad part. It's the only option that exists.
This is very reminiscent of my invitation to play the Mass Effect: Andromeda closed beta a month ago. I was super impressed with the combat, the scenery/level design, the characters, all of it. Then I sat back and thought about it. I thought about what I had seen and done, and what I saw and played was just really sub-par. It wasn't good. Point being, I think people should always take a step back and objectively judge what they're emotional about. You might come to a different conclusion.
