I know with movies that they charge rental stores a lot more and then they get a license to do it. Maybe that happens with games.
I think game companies should support rentals. I would bet game sales would decrease with out it, since £40 is a huge investment for something you might not like and trying it for a few days is the best way to decide. Any sane publisher should give the game enough replay value and length that people shouldn't be satisfied with a 5-day rental.
