This sounds a lot like me, except I'm still in grad school and never got into Elder Scrolls. Otherwise, I echo everything you're saying.A big reason I got out of gaming a long time ago is because they stopped making impressive and epic RPGs. They became more of a commodity and FPS' took over the industry and because I always felt like if you played 1 FPS you played them all I naturally got really bored with gaming about 5 years ago.
I also graduated and had to start working, I didn't want to invest so much time into gaming anymore. I still LOVE the sandbox games like GTA and the open ended RPGs like Skyrim but they seem to be few and far between now.
Above all else I think I stopped gaming because they started to base all the new games around playing online and I simply never liked playing with other people, I always just wanted to play my own game and get sucked into it and I think that's why I loved games like Morrowind and Skyrim and the GTAs. Starting to buy games based around online play really turned me off- Madden is a great example of a gaming franchise that basically stopped improving itself for the sake of improving online play.
Combine my dislike of online play with the fact all FPS' are mainly online now and you have my reason for contributing to the 30%
At this point the industry needs a revolution to get people back... I think we got one about 12 years ago with the XBOX and Halo. We're due again for some kind of reinvention but I fear the next-gen systems will just be more of the same.
A big issue as well is the old console gamers evolved into computer nerds that figured out how to build and update their computer for better value and graphics which is contributing to the decline in console sales.
Its nice to know we may have lived through the golden age of gaming but I don't think the video game industry will go quietly... if it survived the 1983 crash and boomed back for the 90s and 00s I think they'll bounce back from this...
