I just realized: the rest of the family was at that zen salt temple or whatever during the gaming event. Meaning that none of Bart's family was there to watch him, cheer him on, or support him. What the fuck? Even if you argue that they didn't like the game, that's still a shitty thing to do. And far as the ending goes, it really just seemed to be a diablo ex machina to fuck Bart over.
The ending would've gone so much better if, say, Bart's team lost because of him and he understandably feels miserable, but then Lisa takes the family to the temple and uses it to help Bart understand zen and letting things go, thus helping to cheer him up.
