Meh, I don't think the amount of work has much to do with it. Not only do games not exceed a certain amount, but gta is also a very popular franchise. Gta 5 should sell so well that Rockstar won't need to raise the price.
EVEN IF ITS 1000 $ I AM GOING TO BUY IT AND TRY MY BEST TO BUY IT ON THE VERY FIRST DAY, STARTED SAVING MONEY FOR IT A MONTH AGO.. . I AM PLAYING GTA TITLES WHEN I WAS IN THE FIRST ST GRADE........WELL IT WOULD BE AROUND 150 $
