That fundamentally depends on you as a player. If you are a multiplayer guy then you will probably like it. If you are a fan of the old R6 with a proper Singleplayer mode as well as Coop Terrorist Hunt and the like then the game will probably disappoint you.
There is terrorist hunt as far as I know, but more of a reduced simplified version of it. And there is no singleplayer, they went full multiplayer with R6:Siege.
So like I said, it depends on what type of player you are.
Funny comment. But in all seriousness, I don't see how people are still so outraged over that stuff. 90% of game companies "over-polish" and "misrepresent" their games in terms of graphics these days just for them to realize shortly before release that it will not run on the machines properly and downgrade it then.
I mean even the Witcher 3 had a small graphics downgrade. Yeah I know, technically it was a rendering mode change that caused it, but in the end it resulted in a slight drop of graphical fidelity in many people's opinion. Of course for a game like TW3 it's not that bad since they actually have very good content in the game. Story, mechanics, lore, it's all great. But if you have Ubisoft games of which most have brilliant concepts but just a mediocre story and general execution in the end, it just adds to the negatives, it obviously has a much larger impact if the game is also graphically downgraded.
Still, I don't understand why people are still angry about this. For me graphics never mattered. It can look like shite for all I care as long as it plays well, has a good story and is immersive I don't care. I mean I still play R6:Raven Shield to this day.
