An absolute banger of a game to play with a group of friends. Me and a couple of pals started of together from scratch and I've had a blast.
The only downside is how the game handles multiplayer during the story mode of the game. Mandatory assignments have to be initiated solo until the monster is discovered, after which every player except one have to leave the quest in order to team up. This combined with the unskippable cutscenes led to some complaining and groaning which could've been avoided if the game simply allowed for a smoother co-op experience during the story.
Nevertheless, Monster Hunter World is pure co-op excellence
