In the second ET video, his Gamecube wasn't plugged in. Even after playing the first game.
At the end of the (TMNT II: The Arcade Game segment of his TMNT review, he proceeded to open his NES. He then, literally just pulls it out without pushing down on the cartridge to release it. This suggested that he had the game sitting in there unconnected with the power on.
His Cool Spot review had two examples. The first was when he played the Game Boy version, along with taking the Super Game Boy footage and superimposing it onto the handheld, the red light next to the screen is off. The other is during the ending montage, amongst the unrealisticButton Mashing he's holding both a Nintendo Power issue (to be more exact, the December 1994 issue, which didn't even feature coverage of Cool Spot) while he mashed on his controller.
Not a real example of his series itself, but Chris Bores claims that he saw James Rolfe at a convention several feet away, but he refused to go up and meet him "out of nervousness".
People have actually tried to help Bores before, such as giving him title cards and footage, only for him to accept and never use the stuff given to him. Guru Larry mentioned on Twitter that he offered to proofread Bores' scripts, only for Bores to decline.
Schedule Slip: For quite some time now, actual IG reviews have gotten rarer and rarer as he fills his channel with more non-IG videos. In 2009, he only released two retro reviews, three videos on "video game history", and five "Neo" reviews which required little effort because he doesn't care. In 2010, he's released even fewer.
Which is funny because he stated in his Q*bert review that YouTube would fire him if he doesn't post a video every month.
IG started the History of Video Games series in May 2009. As of March 2012, he's only released five parts, covering up to the Fairchild Channel F and the lesser-known first video game crash.
