That's fair, but for many people and reviewers, if a game (not using TC4 as an example, those games tend to have a great deal of lasting appeal) has replay value of two hours and isn't an arcade port, then it's not worth the money if it was full price at retail. I'm sure there are many people who would gladly fork over a large amount of money for a game that lasts a small amount of hours, but I think they would be in the minority, and reviewers cater to the majority first and foremost.Fredrick2003 said:-snip-
All in all though, lasting appeal is important for gamers who can't afford all the AAA titles that come out in such quick succession (employed or not). Much of the time I would assume that it's important to know if this game is going to last you however long it takes for you to muster up some more money to buy the next title that appeals to you, or if it's going to last you two days and gives you little else to return, probably causing you to return it (in which case it might as well be a rental, which I guess lasting appeal could be the difference between that or a buy).
EDIT: Also have you played Portal? If so would you not feel cheated if it cost you however much a full price 360/PS3 game costs you after you had completed it after two or three hours/days?
