No multiplayer is a good thing, it's good to see a few games taking this approach recently! It does seem to have a very quick release date, I only heard about it a few weeks ago on here and it comes out in just over a month.
It's being developed by Ubisoft Montreal but they have support from a few of their other studios, the same way that Farcry 4 did.
I really hope that it's good, there seems to be a few really interesting game features in it so I hold out hope. I didn't really enjoy the Shangri-la missions on Farcry 4 that much and this seems quite similar to that, so I'm a little hesitant but will still give it a go.
Let's hope they don't start churning a new Farcry out every year like they do with Assassins Creed, for me that is what has taken the magic away from Assassins Creed.
