Can you re-sell an open MMO?

Just bought Star Wars the Old Republic out of curiosity (I dont really like Star Wars that much) and after playing a few days I got bored with the game.

One of the very biggest reason is the combat (It's not like DCUO and is really boring for me) So I wanted to buy Tera Online (Which was my real game before I saw SWTOR) and was wondering if I can sell my SWTOR in Ebay or something even though I've already opened it and use the activition code?

Thank you in advance.

So this is a pc game then. Then you shouldn't be able to sell it since the disk is link to your account. I not sure but some programs and games have a deactivate function. You should ask game stop or the actual game company and see if you can. Due to having an account linked to the actual disc it makes it virtually impossible to sell the actual disc when you do finally get bored of the game. A shady practice by the MMO gaming industry, but one that is quite often overlooked.

So why is this even happening? After all, developers and publishers allow you to sell console games. The music industry allows you to sell your long forgotten CDs. Even the movie industry allows you to sell movies to your friends. Why not your pc games.

You have to sell your actual account then. I'm not sure if that's legal in this case or not, but some people do it.

Thanks, I think I'll hold into it. Not going to take that chance. Besides in the future I might like it again. Maybe
