[H] Red Dead Redemption 2 (Rockstar code) [W] Disco Elysium (Steam)

I have a code for Red Dead Redemption 2, but it's a Rockstar Launcher code - NOT Steam.

Would be happy to part with it at a loss for Disco Elysium.

I guess, if this is unsuccessful, I'll open it up to other games around the ~£15 mark.

Cheers.
