Yes, and no. I buy a game if I know it won't be around by the time I can afford the console. (This is back before used stores that sell you the scratched up non-working version of a game, with a fake box and nothing else for only $20 cheaper.)
These days, I'll buy one that I never plan to get the console for, only if it's just really obscure, and I see a really good price. Like, I got the Urusei Yatsura Mega CD game for only $20 once. I've never seen it for sale since or before. I don't plan on getting a Japanese Mega CD, and I can't play it unless I do, but i still like to have the game as a fan of the series.
