I doubt someone here will fund this loan with such collateral, first because you are not saying the ammount you willing to ask, and second because a game account isnt something easy to sell, but maybe the right person can sell it, i know you dont wanna scam or atleast isnt your main thinking, but the lender has to have sure he can sell those things, soo maybe btcjam can be the best option for you, but i doubt they will accept those colateral, usually they lend to people who can proof their income.
