I bought L.A. Noire from a store to have something to play on my way to Los Angeles when... surprise! Game update!
Ok it wasn't really a surprise because of the warning that was one third of the box cover.
The only reason for me to have bought the physical version of a game is that I'm sure I won't play over and over again like some other games. This means that I can just sell it in the used market and get back like half the price of what I paid for it, maybe less. Most likely less.
But I'm sure that companies are strongly against the grey market of used games, so what's the point?
Is it for collecting? Oh yes, I have so much fun collecting small game DVD boxes with nothing but a small game card inside. I have no clue, really.
