My parents always used to buy the games for me when I was little. They were the only things they ever had to buy me, and they kept me quiet and amused all day every day for years. I guess it was well worth the money. All my figurines and plushes (I had a lot of Pokemon figurines, I would guess I had about 230 by the time I stopped collecting) came from birthday/Christmas/random other occasions. Come to think of it, the only toys and games I owned as a kid were Pokemon merchandice.
Now that I'm older I buy the games myself, but they don't cost too much so it's not that big of a deal. I don't collect the figurines or plushies anymore (although I will pick up a Kecleon, Lickitung, Tropius, Shellos or Tangela if I ever run into them. Most of the reason I don't collect anymore is because figurines and plushies are harder to find now-a-days.) Most of that money gets spent on clothes, ramen and pizza.
Ah, how time flies.
