You do realize that it is just as easy to Pirate a game and use it on Console (PS3, XBOX 360 and even Wii). Just go to craigslist look for someone to "Flash", "JTag" or even get a Xkey for your Console (Only saying this for Xbox 360 as I've never used ps3 but I know you can pirate games if you jailbreak it). $20 to flash about $150-$500 for a JTAG and $60-90 for a Xkey. You then can Pirate a game, burn it to a disk with xbox backup creator, and img burner. After you have successfully burnt the game, put it in your console and BAM! You have a Free game that works as if it was just bought from a store. So Both ways this doesn't affect there motivation to put games onto the PC Platform. This is also how people mod Consoles.
But yeah, So the whole "Higher pirating rates gives devs less motivation to bring games to pc" is incorrect.
Fun Fact: Pirating, Modding, and burning games only takes about 6 hours (Depending on your internet speed to download the pirated game, but to burn it and all that it only takes about 1 hour).
Anyways, my rant Is over don't even think it was a rant.
OP. I do think that Pirating games isn't a good thing. I have done it (For console) but I was stupid then and didn't realize what trouble, and how unfair it is to the devs. They do put there hard work into it and DO deserve respect/some income from that. Otherwise its like a F2P game. Now COD on the other hand. Pirate away no "Hard" work put in there simple CTRL+C and CTRL+V for them.
