You silly internet people are arguing about prices for systems and upgrading them. Just thought I should mention, consoles need parts and crap too. Controllers, obviously, but occasionally you might want a wireless controller, or maybe you bought a 360 (hardy-har-har) and you realized that you have to get your HD-DVD drive separate. Thats pretty expensive if I recall it, plus people like buying component cables, wii-remote addons, and bean bag chairs.
On top of all of that, there is the cost of games that everyone is leaving out. If you want a console game, you buy it, then you stop playing it when it gets lame. If you want a PC game you buy it, or steal it if you're thrifty...er... "A DIRTY FILTHY CRIMINAL THAT WANTS TO GET ACQUAINTED WITH BUBBA IN JAIL BEFORE HE GOES TO HELL FOR DOWNLOADING MP3s/movies/games/hotpockets". ~~(not an) Actual quote from the RIAA
(In no way am I advocating criminal activity, but I would be a liar if I trivialized the amount of content that gets downloaded\stolen off the internet) If you're not a crook and you want more game for less buck, you can always download freeware games and Mods whereas if you're a console-guy you need to shell out more cash. I'm not even going to get into the addons and patches that are released for PC games even though that should also be taken into account.
So since the price of equipment is equaled pretty well now that consoles are selling addons, and the amount of game you can get for your money is tilted so heavily in the favor of the PC that even Hillary Oprah and Rosie couldn't change it by jumping up and down on the console's side of the price scale, I think its fair to stop claiming that PC gaming is more expensive.
