I don't really know all of his transgressions off hand, but I do know that he's one of those people that constantly stood out as a prime candidate for being way better off not having a Twitter account because he doesn't seem to have a good internal filter for what not to carelessly state publicly in 140 characters or less.
He also has a poor filter as far as input goes. He obsesses over what people say about his reviews in the comments despite clearly thinking that they're filled with crazies. Which is probably true, but he can't help obsessing over what they say anyway. In fact he'll call them a "vocal majority" as they are throbbing with attention in his mind. Engage dismissive maneuveurs!
Thing to remember about Arthur Gies: Arthur is always right. Strikes me as the kind of guy that has a Google alert set up.
The most recent thing I can remember is his this:
http://www.neogaf.com/forum/showthread.php?t=524733Gies took thousands of dollars donated to Anthony Gallagos by GAF members and bought himself a gaming PC. Then he leveraged friendships to get a foot in the door.
Nooo, slow down there. He's obnoxious but there's no reason to make shit up. The money was donated to Rebel.FM, formerly 1UP.FM. They got a lot more than they expected, bought all the gear (Macbook for Garage Band, mixer, headphones, mics, etc.) and then just sat on the rest and used it to buy dinner for whenever they recorded. The original cast was: Anthony Gallegos, Phil Kollar (who now works at Polygon) and Nick Suttner. Arthur tagged along because they were recording in his (and Anthony's) living room, so whatever. Pretty sure people started disliking Arthur pretty much immediately, btw.
Later on Tyler Barber, a friend of Nick's also starts appearing on the podcast. Then Nick and Phil eventually leave because they find employment. Nick goes to Sony to scope out indies or something (and can't podcast as a result), Phil ends up at Gameinformer (and moves, so he's out too). Tyler Becomes a mainstay.
Anyway, to cut this short, they start talking about PC games and since Tyler was a poor freelancer at the time and never really played PC games they dipped into the money pit and bought him a gaming PC so he can contribute to the podcast more. Which he ended up doing. They did talk about it openly on the podcasts. I don't know if they announced it beforehand, but it was never some sort of secret.
