£50 for a quality single player game which has a campaign of at least 30 hours and lots of replayability, full included content no DLC, and you know before you buy is good from the playable demo not such a big deal.
But in an era where we rely on hype from biased media, and the DLC can cost more than the game, and single player campaigns are not the primary focus anymore I think yes £50-60 is a joke.
