stonebro: I'm not sure how I'm going to handle this. One way is to just trust people on this here fine forum.
Probably a screenshot would suffice. Even if you have a gargantuan gog collection that for some reason does not yet feature Tex, there are Firefox addons that will screenshot the whole page for you, for example.
Or if anybody else has a good and relatively hassle-free idea of how to validate that a potential winner isn't running away with my code for nothing, I'm all ears & tentacles.
Maybe you can ask the winner to add all the Tex games to his/her wishlist (first remove them if they are already in the wishlist), and post a screenshot showing the wishlist with the winner's name. You cannot add a game in your wishlist if you already have it. You also only need one small screenshot as you can show the wishlist by addition date, so the games will be on the top.
An example here.........
