Worth trading in?

Hey all, I have a Wii U and Mario Kart 8, Super Smash Brothers, Bayonetta 2 and Super Mario 3D World.

My question is, I work at gamestop and this friday starts our employee trade in bonus where I get an extra 50% trade in credit.

Im thinking if I should trade in my games and get some bonus credit. I don't have anyone to play these console games with because my wife doesnt really like them.

What do you think I should do?
