i don't think the most recent comic is a great example of their microsoft bias. and i don't think it's as much of a microsoft bias as it is just a "appease the populus" mindset, and microsoft happens to be popular now.
just look at their posts (not just the comics) about MGS4 and then compare them to their posts about halo 3 (two games they dislike). they are cautious with their language and reach out to halo fans, and then for MGS4 they write the most convoluted, elitist, condescending shit you'll ever see on their site.
i never said it was a conspiracy--i've just pointed out how they do show a clear bias. it's not a tin foil hat theory so troll someone else. only an idiot would look at penny arcade as a neutral, objective party--the problem is that many people who agree with PA's opinion like to give authority to PA. PA are very much like anyone else on the internet posting their opinion, and yeah, it usually involves a form of bias.
the 3 month ban i got just shows how horribly incompetent neo-gaf's community management can be. a 3 month ban for disagreeing with an opinion on a discussion forum--absolutely ridiculous.
