How does the customer know whether the salesman is giving him good advice or just trying to push some POS game for other reasons, like higher profit margins or pressure from management?

Which is pretty much true anywhere a salesperson is involved. At least with video games I never feel like when I am at the store I HAVE to buy a game right then. If I see a few that look good, but I am not familiar with them, I can come home and look for some reviews and screenshots and be able to make a more informed decision next time I am out shopping.
