So essentially, Yahtzee had no complaints for Overwatch.
His points were flawed:
1. Overwatch being overpriced is false. It's $39 base price for PC. $60 for special edition, which is the price of a NORMAL game. The price for the console version is $60 as well. Plus, considering he paid $70 Australian dollars for it, that means he bought the used version for a value of $52 USD. So calling it "overpriced" is an outright lie, especially for such a polished game with tons of essential FPS features, including the ability to save individual settings for every character and customize nearly every aspect of the settings for them, down to the smallest detail like reticle color.
2. The micro-transaction complaint is moot as well. The whole loot box system allows everyone to earn the cosmetics for free. If you have extra money you can choose to have all the flashy skins sooner, but that's entirely optional and in no way needed to enjoy the game. The default models, including the easily won skins through the loot box, are very satisfying.
So ignoring the non-sensical "overpriced" and "micro transaction greed" complaints, his only gripes were the simplified lore and the Tracer butt pose change.
TF2 didn't have much lore either, but that didn't stop it from being the greatest class-based shooter of all time. So that complaint, although valid, is beside the point. The butt pose change had Yahtzee arguing about loss of art direction, however the replacement pose was even better from an art direction standpoint as well! So Blizzard clearly cared about their game, but Yahtzee conveniently omits this fact and talks about how responding to "one" complaint is somehow indicative of Blizzard not caring about their game. Pessimistic spin while glossing over the good points is not fair judgement and really is more telling of Yahtzee's poor reviewing skills.
My main takeaway from watching this video is that Yahtzee found Overwatch fun, and he wanted to say it in a way that makes you think he isn't too crazy about it with a bunch of nitpicky side arguments of non-issues. He sure knows how to please his fans, but objectively this was a shitty review and pandered to those who just love to hear Yahtzee complain for 5 minutes.
