I don’t think you’re at all informed on the facts. PC gaming isn’t going anywhere; consoles bang the drums louder, but its a fact that PCs are still very much a defining staple of the genre.
PCs have one MASSIVE advantage over everything else; you’ve already got one. You NEED a computer to live in a First-World country; not having one is social, economic and political suicide. You can’t live, work or engage without at least one type of electronic device, and that device is almost always a computer. The advantage is that, since you’ve already got your email computer, you can put games on it no problem without having to buy any more hardware to make it run. Its never too pretty, but it’ll work.
For consoles, you have to buy an EXTRA computer that does NOTHING for you but play games. That means that gaming companies have to make you WANT to buy a console, but they don’t need to make you want to buy a PC; you’ve already got one.
Meh, it’ll all converge to a point where we’re all confused about how we got on so long without it being exactly the way it is at the time. I can’t even remember how I lived without my iPhone, and I only got that about 6 months ago. Society rarely develops in a way that makes things work for us LESS, and I’m entirely confident that this trend will continue for gaming.
