Question

Game is rumble fighter and Maplestory

as far as I know majority of online games, there is a email recovery or you can even contact the customer support of the game. have you tried either of those?

Nope havent tried ill try right now and ill tell you what happens~

edit: for rumble fighter i was able to remember my Security question so that means if i give the buyer the answer they can change the email,
and for maplestory I know my Date of birth and such so the buyer can change the Email and add a security question since they can add it.

Can I still trade this?
