Does Walmart let you return a game that you've already opened to exchange for another game and I do have the receipt

Yes

No I don't think so

I think all opened games have a non return policy .

I dont really know. They return on about everything else.

Im not sure. I would call customer service and ask.

Yes with a receipt

Yes they do.

If you have all the pieces , it's obviously not been used and of course the receipt. Should not be a problem.

If it's opened you can only return if it's defective for the same game.
