It's hard for me to tell since I've been here a few years now. So much has changed in my life since coming to CAG, that I don't know how much I would be spending on games. My guess is, as money has gotten a bit tighter in the last couple of years (making more money, but expenses have skyrocketed).
My guess is that, overall, I haven't spent more money (though, some weeks I definitely have), but I'm getting far more games for the money I have.
