Easily one of the best games I've played in the past 5 years. I went into it expecting a "merely good" Sony exclusive, but enjoyed every minute and bought the frozen wilds dlc immediately after completing the main game. Great story, great graphics, great gameplay, great mechanics. It's not revolutionary, but damn it's fun and engaging.

EDIT: p.s. Dunno your philosophy on gaming, but I played it on easy mode so that I could focus on the narrative and blow the crap out of the dino-mechs without too much stress.
