does it have to be a game?
i remember when i first started playing 'Magic: the Gathering' i made some trades i keep kicking myself in the balls for...
but then again, skinning the newbies for all they're worth is a time honored tradition, one kid had borrowed his brothers rare folder for the day, probably with instructions to trade only certain cards... a flash of a shiny (yay, shiny!) fatty (big creature) and he was all to happy to hand over his Shiny Damnation...
for those who dont know, damnation is good, very good, that kids brother probably strangled him, and then ate the corpse.
im a bastard, a bastard who booster-pulled 5 tarmogoyf in 3 weeks (all magic players want to kill me at this point) yeah, just wait till they're second printing rolls around (future card, thats right the GOYF REPRINTS!), im'a going to make a killing (or it will fall second to some other card, and i feel stupid with a pile of $4 junk rares)
sorry for that, just getting it out of my system
