This is not as true for me but I'm sure it is for some. This is just a story as far as I go.
Game Y ran somewhat smoothly on my PC. I couldn't run it smoothly on max so I settled on medium. Now with Game X's increase on the minimum requirements I need to buy new computer parts just to play this game on low. So now a computer game that cost you $60 on your console will end up costing me more than $200.
This marks the end of the story.
I always figured that the reason PC games were cheaper was because the cost of the "console" was higher and needed to be upgraded for games to run on it.
If tomorrow Activision announced that to run the game on consoles you HAD to buy a certain $50 accessory, no way around it, console owners would lose their minds. And this is only $50, not the 100's a PC gamer has to shell out to play modern games smoothly. 5 games at $50 made up for this. Granted the cost of a PC game never actually equaled the cost of a console game when you include the console, you would have had to buy hundreds of games to make up that cost, but to me that is what always made them equals at $50.
Add on to that what was mentioned earlier about Activision making roughly $10 more per game on PCs than consoles even before the hike, and you see that PC users are already kind of fucked over, and now they want to fuck us over more.
This basically screams to us to move to consoles, not that they haven't already (Online multiplayer being one reason for some games. I'm looking at you Ghostbusters.). While I'm not against consoles, I do love my 360, I just prefer my games on PC when I can.
