The overall story this season felt a bit tired and aimless. The tension and energy of the previous seasons is missing, and in the end, several characters just end up back where they started. A lot of the good things about the show are missing this season.
The gaming world used to be integral to a lot of the stories, but now it's more of a backdrop - the fact that the characters work in the gaming industry is no longer as important to the stories, which made the show feel more generic. The first season had fun and original stories about things like dealing with unpredictable teen streamers with a huge amount of power over the game, and players using the game to promote nazism. This season had stories about things like christmas parties and brunch.
The show has also become much less grounded in reality. It seems like anyone can just decide to work anywhere they want - changing your profession is as easy as changing your hat. Ian and Poppy don't seem to have any plan for building their company and just do whatever. They start by reject a huge investment offer, because of an unexplained gut feeling, and then money doesn't seem to an issue until the end of the season. Meanwhile, they rent a gigantic futuristic office space but don't hire any people to work there. And they're supposed to be two intelligent people with a lot of experience and prior success in the industry. In short, there is a feeling of "anything goes" and "actions without consequences", which reduces the tension makes it all feel a bit empty.
The group dynamic of all the characters is another loss, now that they are off doing their own things. A lot of the friendships introduced this season feel rushed, because they didn't have enough time to set them up beforehand (maybe it would have been wiser to not separate the characters until a later season). Also, the departure of F. Murray Abraham was a huge loss for the show, he was always hilarious and had some fantastic character moments last season.
This season saw a major change to its formula, and I don't think they managed to pull it off, but the show survives because of its well-developed characters and good performances. Hopefully, the show can find its way back to the quality of the first two seasons.
