How to get good at games?

Not just good.  Pwnage.  As in Japanese/Korean pwnage (sorry, but I needed an adjective).  The Sai-GARest of gamers everywhere.

Just play games, any games, as often and for as long as possible until you know every single one you own inside out.

If your serious about being incredibly awesome, make a point of not buying/downloading any more until you finish the ones you have.

Sound like a lot of work and effort? thats because it is.
No short cuts I'm afraid. Also, the sad truth is, no matter how blindingly good you get, theres all ways going to be people who are a shit load better then you.
Not just one or two people either, but hundreds, and they'll all be able to kick your ass at everything no matter what game you think you 'pwn' at.

Sorry, thems the breaks.
