From the sidenote in the above, I have adopted a system for when it comes to DLC/Games and the kin.

I argue that "good value entertainment" should be able to occupy my needs for $1/per hour as the 'acceptable' bar. So if I went and bought a game for £10, I expect to get roughly 10 hours worth of entertainment from the product to be worth the purchase.

You could easily argue "This/that and the other is cheaper" and you are right, there are activities where you can get better than $1 per hour, but unfortunately, there are far more activities which cost well over this amount but I feel that $1 means "Money's worth" from these kind of products.

(Though, it ends up skewed if you added a game like World of Warcraft into the mix, as that is $10 per month, and average player plays 100 hours per month, so $0.10 ph)
