I've been playing the game since early access on PS3. I did beta 3 and 4 on PC. When I say that I'm playing on PS3 pretty much everyone in the entire game has the same reaction. "Why the F**k would anyone ever play this game on PS3" Which is usually followed by some sort of BS about graphics. (which is probably the absolute LEAST important thing to me when choosing a game to play btw).
Short version, because my PC isn't powerful enough to run the game smoothly. It kept overheating and I had to turn the graphics settings almost all the way down just to be able to even move my character.
Long version. There are things that you need, and things that you want. I NEED to pay my mortgage. I NEED to pay my utilities. I NEED to provide food, shelter and clothing for my children. I NEED to pay my wife's tuition. I NEED to pay my car payment. I NEED to pay my car insurance and gas for two vehicles. I DO NOT need a new computer, especially if it is just to be able to play ONE game. I'm not the richest man on earth. I'm not poor, but then, there are things that I need, and there are things that I want, and then there is paying hundreds, perhaps thousands of dollars on a computer I don't need, or even really want. Especially when the game I want to play is also available on a system that I already own. I could buy that new computer, but then I would have to take money out of the account I set up to save for college for my children. Sorry boys, daddy wanted to play video games so you can pay for your own college. Or I could take money from my rainy day fund. Sorry boys, daddy can't afford to fix the roof because he would rather be playing video games.
Do you see what I'm getting at here? When you move out of your parents' home, and provide for yourself and your family completely, without aid from your parents in any way, there are far more important things to spend your money on, or put it away to save for. Why would I spend a few thousand bucks on a computer that would mostly be used for MS office and internet surfing, when i could just as easily play this game on a system I already own and be quite happy with it?
So, the next time you feel the need to belittle someone because they choose to play on PS3 instead of PC, maybe you should ask yourself if maybe playing a video game in full resolution/graphics mode might not be the most important thing in that person's life. The happiness and security of my family always comes before leisure activities that I can live without.
