Adverts.
There doesn’t seem to be much cash in advertising PC gaming any more. Rock Paper Shotguns current ads are for some university and easyjet. Blues news is pimping crisps and heroes and Sky Plus. I see a spore advert on gamespot, but not much else. Quartertothree is advertising gold farming sites.
There was a time where the latest FPS, RTS or other high profile PC game was advertised everywhere. These days, its online only, console games or casual games ads only. Is PC gaming really this sparse? At least there is a (slim) chance this means cheaper advertising slots abound?
