Now I feel bad... I want more potential free money, Gaben!
(I also don't want to think about what your initial investment would be for that many drops
At least 50 card games or so were in cheap indie bundles, so maybe he didn't spend that much. I know this because 99% of the games on my boyfriend's Steam account are from indie bundles I've activated and I still need to idle over 50 games there and take the cards for myself (but I haven't even finished idling my own yet).
On that note I've stopped crafting badges for games where the cards are worth 40+ cents for weeks now and started accepting the money Valve's been trying to give me. So far it's paid for Spelunky & Guacamelee for myself and Castlevania for a friend.
Edit: This also reminds me that I've kind of started secondarily collecting games on my bf's account in addition to my own. Help me.
