It is one of the harder careers to level for this reason, and provides less money per day in salary than certain other Careers. Note the jumps in skill level requirements from Video Gaming to Charisma, Comedy and Mischief. You need to play games for a few hours in order to gain followers, it tells you how many you've gained when you stop playing. The Prank Streamers (under social networking) and Let's Play (under Play Games on Computer) contribute substantially more followers than other means of social networking - pranking in particular contributing hundreds of thousands when it goes well, though it does have a cooldown. The most significant difficulty here is obtaining followers, but thankfully you are given many means to do so - knowing you need many more for each level should help. The ideal mood for this branch is Playful. Playing games for a few hours, they can pick up 100-200k followers, then advertise products on social media to make thousands of Simoleons.
