Wait, crap.I forgot.
I'll remember it!
OH! TRADING!
Like, I remember wynn saying we couldn't trade something with someone that we got from the store if it wasnt of equal value.. but since you dont know when the person bought it, values might've gone up/down.. And they could lie to get something worth more..
So, what's the big problem with trading unlike valued items? If i had a serval, i might want a wolfdog.. someone else might want a serval and have a wolfdog..
