I think I'm original in this, but maybe not. I came up with a new word today while browsing my Xbox Live gamerscore in comparison with friends.
I submit to you: gamerwhore.
I think to be a gamerwhore you should compare your gamerscore to others frequently (I do), but you should have also played NBA Live 06 and King Kong (I haven't).
UPDATE 03/01/2006: what timing! Major Nelson also says something similar on his blog yesterday. Great minds think alike…
