Greetings! Some torrent trackers do show the downloads number. Checking Mininova, for example, it has ~180.000 CoD4-PC downloads for the most popular... "versions". Once you imagine the numbers from other torrent sites and other P2P delivery systems you get an idea on how prevalent P2P freeloading is. Console games are more expensive and they sell better. If you find PC games are too short, change genre. Total War games, for instances, would have to be priced at $1.500€ for them to have the same price/hour ratio as Crysis.
