Theres no doubt in my mind that on everyones list, they know what they will and wont trade of theirs for what they want of mine. If i break it down to wanting one specific system only and i get random "CML" replies i wont do it, if someone says "CML, the only games i wont trade are xxx xxx and xxx" then ill look, i know whats not ft and what they say is.
Too many times people just say cml and when i do its either gone already, they dont wanna trade it for what they want. To me its a waste of time. be up front with what you wanna move for it and dont dick around. sounds harsh but i dont wanna waste anyones time as much as i dont want mine wasted.
