There's this guy at my school who is The Nintendo Fanboy. He takes it to absolutely delusional heights.
He claims that the Wii is more powerful than the 360 or PS3. He says he "took them apart and looked at the parts inside." When I asked him which parts he supposedly compared, he said, "The motherboard, the RAM, the hard drive?" and trailed off. The Wii doesn't have a hard drive, and it is demonstrably less powerful than either console.
He said that he compared Modern Warfare: Reflex to CoD4 side-by-side on the same HDTV, and that the Wii one looked better.
He was bragging about having super high scores online in MW: Reflex as well. I got his friend code, and had my friend who has the game as well verify his claims. He only had two kills total.
After E3 2009, he told me that Bethesda announced a sequel to Fallout 3, exclusive to the Wii, at said E3. Googling showed nothing, so I asked him for a link. He never gave me one, saying that they had "deleted the article."
He claims he's had personal conversations with "the head of Nintendo," "the head of Sony," and "the head of Microsoft." He never names them.
He claimed back in May or June (it was about a week after CoD: Black Ops was first shown off) that he had an early build of Call of Duty: Black Ops. He claimed back during the Halo Reach beta that he already had a build of the entire campaign.
I know the kid is just probably a habitual liar, but others don't. Other people cling to his every word as gospel. Every day at lunch, he has a group of five or six people he preaches endlessly to about Nintendo.
Now, this wouldn't bother me except, he won't leave me alone. I used to try to be nice to him, but eventually lost patience. Even now, as I actively show my dislike for him, he continues to bother me. He constantly tries to engage me in "debates" about which is better, Sony or Microsoft. He seems more like a troll than a fanboy, actually.
