At the risk of sounding too harsh, hopefully it won't take eight months for you to realise that saying that you
is a bit wanky itself...?
I'd like to think games journalism is no different to music or film journalism; there are plenty of people can write adequately, but it's about having encyclopaedic knowledge, an ability to cross-reference everything and see the broader picture of the whole scene, that sets you apart from a say-what-you-see critic to must-read reviewer.
That is to say, pretty much anyone could do it to a certain standard, but to be really good is pretty hard.
Listening to Shane on 1up Yours, when a few of them are desperately trying to recall some twenty-year-old game that's inspired a trailer, and he cuts in to coolly list its metacritic score, boxart illustrator etc. is impressive to me. But then you hear a whole roundtable asking about whether or not the new lightsabre wii game uses 1:1 and they all just go "duuuuuuuh, dunno" and you remember that they're all just nerdy cunts that write rather than proper journalists anyway.
