I hate not knowing the games in case I already have it so I guess I'll go the safe route with 2-11, jonnyp11 on steam
Just saying, you could draw 4 winners and let them know the games, if they can't reach an agreement to who gets what then you can randomize that part, but if someone has them all or doesn't want one then they can let you re-draw for their spot
It's a gift so it's not a problem if you know or not the game. Secondly if you already own the game you'll get something else instead, it's written in the post
