I work in a comic shop so I've got easy access to comics and gaming cards like Magic. No matter how much I try to resist, all of the people who come in to talk about Magic always convince me to spend some time playing. It's addicting.

I also play video games, run every morning and I do a lot of craigslist. I collect Final Fantasy VII and Final Fantasy Tactics (original for PSX) and I find killer deals on these every now and then. Sometimes I can buy collections of games/systems and keep a few games, then resell for the same price or more. Before XMas, when there was no faith in the PS3 game library, I could buy and sell PS3's for about $100 profit a pop, but now nobody sells them cheap.
