I guess it boils down to preferences once again. Personally I dont look to buy a game and complete it quickly, to then wait around for more levels or additional material to be put out again later. I prefer the route of a long game that takes a while to complete in the first instance. I think that is much more enthrawling. Take HL2... great graphics and a great engine but after over 4 years in the planning the actual time it took to get through it was less than a week.... and to me that is poor!
