I've been playing this game the past 2 days and already clocked it at 13 hours of gameplay (19% complete). While it's nothing special in the open world genre (mix Rage and Shadow of Mordor), the Mad Max-atmosphere is very well done. The game makes me keep coming back for "just one more mission", but suddenly 3 hours have passed. Reviews are mixed (ranging from a 5 to a 9), but I'm enjoying it a lot. Avalanche (Just Cause) showed they have a lot of love for the Mad Max-universe. The wastelands look great and Chumbucket is probably one of the best video game sidekicks ever.
The PC-port is very well done. It runs smooth as butter and my 970 can run it at max with 60fps. It's currently cheap on cdkeys.com, price varies between 15 and 20 bucks.
Also, if you plan on playing this, leave the blur option on. I usually despise this in video games, but in Mad Max it's very well implemented and adds to the atmosphere, instead of being a visual gimmick (which gives you a headache).
