Multiplayer wise, one of the most influential games of the past 20 years. The whole multiplayer survival thing? Day-Z was a mod for this game. Battle Royale? Guess what Player Unknown was making prior to PUBG.

The campaign is a true story of love and loss. And a complete buggy mess, but the more sandbox nature of its design combined make it really quite enjoyable in co-op.

Incredibly powerful editing tools to boot, maybe not the most 'fun' fps in the world but boy it is an experience.
