ABH20: Also popped my Market cherry and sold a bunch of cards. Used the dosh to buy some cards I needed to complete a few badges on a whim, which netted me more cards which I sold and I can tell this is not going to end well for me.
BoxOfSnoo: I just made the connection with the cards and the market myself too. I only got about $5 but that's almost like free money.
I tried buying & selling one, for kicks, but ended up losing a couple cents on it... it's hard to track the live prices on anything not in the top 10. However... if I made a few cents on it then I would have been addicted, I'm sure... maybe it's best.
Me too, not really interested in crafting a badge before, but the high price of summer cards really tempting to joining play a little sell-and-buy game (for fun and increasing some levels). If you really want to take a shot gaining profits with card though, you need to boost your steam level as high as possible, to increases your drop % rate. My friend has level 170+ profile and got foil card from some japanese game so rare, it's priced almost $30 in market o___O
What I got through steam summer sale:
Skullgirls > Has one of the best fighting tutorial explanation especially to newcomer in this genre, I'm impressed.
Sonic AllStars Racing Transformed > Impulsive buy because of a temptation to replay some Crash Team Racing genre.
Left 4 Dead 2 > My SISTER insists me to buy it = ="
Strike Vector > Unreal Tournament got married with Strike Suit Zero. I still wonder how come an indie dev with only a few guys able to come with a game as great as this. People is amazing.
Still have one more wishlist to buy, but I think I'd skip it for now because the price isn't cheap enough:
Astebreed > SHMUP game from guys who developed Ether Vapor Remaster.
