I used to think that computer games were an expensive hobby when I was a kid, but actually it turns out that they're cheap and I was just poor. I spend about a thousand dollars on a new PC every five years (there's no point in doing it more often because the console life cycle holds back PC graphics) and a hundred dollars a year on games (not because I'm trying to save money but because I like the sort of games that I spend hundreds of hours playing so I don't need new games often). So the cost of my hobby works out to less than a dollar a day.

Cars, on the other hand... I sold my old BMW 328 for parts earlier this year because it needed yet another $2,000 repair and that simply wasn't worth spending on a 17-year-old car that wasn't in great condition. But I miss that car so much... I refuse to buy anything that doesn't have rear-wheel-drive and a manual transmission, so that leaves me very few options these days, and those options aren't cheap. Often I think I should have just kept spending the money to fix that BMW since there's no better alternative.
