I listened through that whole playlist a couple nights ago I think, but I can never finish XD as like at least 4 of those are like really great.
And yeah, Amy's partly pissed that GlaDOS admittedly cheated against Amy for self-defense (while Amy was under the account name "DarkDescent"), who insisted on playing GlaDOS, and that only Amy was reset by thibault and not GlaDOS. That's why he spends so much time talking about "thibault" and "GlaDOS's asshole" and various phrases mixing the two.
Always fun talking and learning some things from him, but it can get boring kinda quickly sometimes XD.
It was GlaDOS' decision to not play higher than 2+0 games, but DarkDescent wouldn't budge and insisted on 3+3 or anything else with enough time for him to cheat. He insistently kept calling GlaDOS a chicken/coward/pussy for refusing to play 3+3 instead of 2+0 until he finally agreed.
