I think that you should sell your game for keys, and then buy what you want for the keys, since Life Is Strange Complete is cheaper than Metal Gear Solid V, as far as I know.
i was willing to do this but u have not any rep and why 1 would willing to go first in your case? even if u go first the person will get scared bcoz u can go first and can use the key just after taking keys from him thnx have a good day
Because you have no rep here, you'd be expected to go first. That said, you may want to trade with a high-rep person first for something as high-value as that game, because some assholes could try to scam you.
Trading away that game for key currency and then trading for Life is Strange may be your better bet, as it's only about half the cost or less of MGSV here.
I've never really dealt in keys, so I'm afraid I don't know what they're worth
Metal Gear Solid V The Phantom Pain (Nvidia redeem code)
Life Is Strange Complete Season Episodes 1-5
or Grand Theft Auto V (if you're feeling generous)
Not sure how most people here do trades involving game keys, the guidelines and FAQ don't seem to mention this. But seeing as how one could easily screw me over if I hand over the key too early, I'll need you to gift me the game before I send the code.
