I don't think pc game is dying at all, there seem to be more pc games than ever.
I remember a time when you had to leave your house and go to an arcade to get access to the latest and greatest games, no console or pc could compare.
don't forget, all these console games are made with pc's. That is to say, pc's are the tools w/which video games are made, console or otherwise.
I have a ps3 and i like it just because i can access games that license agreements restrict to console (valkyria chronicles, disgaea series, etc..). But only on my pc do i have things like dwarf fortress and dungeon crawl stone soup, league of legends and its like, tons of user made mods for games that are built for such, etc... And where do many developers come from? Many start out as modders or indie game makers on the pc. They often don't become evil until they sign w/ubisoft or EA buys them.
ubisoft recently poo poo'd pc gaming and said its gonna go console only. But remember, ubisoft is a publisher.
I see it like netflix. Netflix comes along and changes the way customers see and prefer to watch movies. Rather than go along w/the change, companies like blockbuster video decide to try and lobby and make services like netflix illegal, try to make customers who use services like netflix into criminals. Rather than adapt, they try and force the consumers to remain *their* consumers, whether they want to or not, so they can keep the gravy train going. Rather than compete w/netflix, they try and get legislators to make netflix go away. Blockbuster paid the price for not adapting. In this instance at least, innovation won, innovation was allowed for and protected by law (and its an ongoing struggle we see in many industries w/often much less pleasant results).
Anyways, like blockbuster video, ubisoft has a case of sour grapes, they get someone like Steam to come along and introduce a better way to sell games that customers prefer, and rather than adapt, they take their ball and go home to the one place their way of doing things still works, the consoles - sort of (even consoles are increasingly involved w/digital downloading). So valve isn't selling their games via ubisoft since they own steam, stardock made impulse so they weren't, now there's even origin, and lets not forget d2d, matrix games, gog, etc... and steam lets indy developers sell on steam even now, so who in their right mind would get ubisoft to sell their game for them on the pc in today's world? I think they left pc because they had no choice. Who wants a bloated publisher that has more employees than sense take a giant cut in order to get shelf space, and create a physical product to create and ship and put on that shelf, when instead they can just-say-no to told style expensive publishing and they can digitally distribute in a world where more and more customers are buying their games digitally.
Old style publishers are dying, and rather than adapt, like steam/impulse/d2d/origin/etc... they are increasingly putting their eggs into 1 basket - the consoles. A last ditch effort to survive. For now, it'll work, but as i said, even consoles are getting into digital distrubution more and more. Even w/consoles, I can make a game and sell it through psn, why let ubisoft take a cut, why let them take a piece of my pie.
I don't know if ubisoft is public, but if it is, i'd get away from its stock.
