Bought it yesterday and spent about 4 hours on it. I can recommend it. It’s lots of fun and the scenario is... well... not too bad :)
You do need a pretty massive configuration though. I run everything almost maxxed out (except the anti-aliasing) and I jumped between 35 and 60fps... Not fantastic... (i5-750 with a R9-280x).
I also had to upgrade to 16gb of ram today as it lagged with the 8gb I had until now. No problem since the upgrade though...
Anyway, if you have a good configuration, go for it, it’s lots of fun!
Oh yeah and I forgot: the game is 51gb to download lol
