The problem with this kind of debate it's that it's ultimately just partisan talk.
PC gaming isn't "dying", but the relevance of the PC gaming platform in the hardcoe game market is fading. When games like TES generate 80%+ (sink that number in your brain, and ponder it) on FRIGGIN CONSOLES, you know something is off.
Budgets for videogames skyrocketed. In a world where developing Skyrim costs hundreds of times as much as what developing Daggerfall probably did, the PC gaming community, for a variety of reasons - from piracy to "who pays games 60$ lol" to Steam sales to size - doesn't sustain a market anymore.
The Witcher 2, the biggest PC exclusive of the year (barring Blizzard games that still didn't sell much more in the West), reached one million sales in six months. Uncharted 3 and Gears of War 3, two big console exclusive, shipped almost 4 million units EACH in the first WEEK.
We're not talking about change. The difference in income is insane. And those sales are full price.
I like PC gaming as much as everyone else, but you can't be blind to this. TODAY, the things who make money on PC are 1) MMO and 2) Facebook games. Like it or not, we've come to this.
This is true but I don't think it's really news anymore and it doesn't mean "hardcoe games" are just going to stop being made for the PC. Many devs will just port console games to PC as they've been doing, and it'll svck a bit for PC users, yes, but PC will still get some of the best games - or at least some of the most visually impressive and technically demanding - as exclusives because so much more can be done with PC hardware. There's a demand for such games. The only game I really feel like I missed out on by being a PC user exclusively, in quite some time, is RDD. If I were a console user exclusively, that list would be much longer.
