I wager that in 2 years you'll still be wrong. Linux has never been and will never be a viable gaming platform. Game makers follow the money and since Linux will never be a mainstream OS there will never be a market for Linux gaming. /thread
I'm sure that's what people used to say about Linux in the mobile platform as well. Then Google stepped in. They had great resources, bank account and a vision. Look how it is now. Of course Chrome OS didn't do so well (and I doubt it ever will in its current form).
So 2 years? Not a chance. Never? We'll see.
I agree with Guest. Linux is only viable if everyone are onboard. At the moment, it's only Valve and Valve's own back-library. Where are Rockstar, Epic, EA, Ubisoft, Bioware, Blizzard, Eidos, THQ, Capcom, Square-Enix, 2K Games, Codemasters ?
Unless these companies join up then gaming on Linux will be limited to Valve, Indie, and the free stuff.
Other things that will never happen include,
Valve open-sourcing their client - I doubt this is ever going to happen, Valve will lose control of their own client, DRM will be stripped from it, and a myriad of different versions will be out there. How many game companies will hop on-board a open-sourced client without even a single layer of DRM ?
Free games - Lets face it, you are going to have to start paying for your games because never in a million years will these companies adapt a different strategy and give their games away. Not going to happen. Indie or Kickstarter, perhaps, but not the top Rockstars, Epics, Ubisofts. etc..
Open-sourcing their games - Again, never going to happen. Plus, to me anyway, I don't see how it benefits anyone, but the ones who want this. Oh but were told that the community can improve the engines, fix bugs,and add improvements, well if you could do all that then surely you would be working for them, would you not? I mean, these top companies don't hire anybody, they hire the best.
No DRM - Again, I really don't see this happening. Game companies need a layer of protection, even if one layer from Valve's own client gives them that 1-day protection from piracy, DRM is still going to be required if you want the top companies on-board.
