It sounds like OP just wanted to play video games. I've been there in my life, so I can relate. However, it's a tragic use of time that could be spent exploring the world.
I did 3 months backpacking in America's best national parks. There were so many amazing experiences I'll never forget. But most of all, the feeling of freedom.
My life will never be the same after doing that. Of course, it's changed for the better.
You absolutely should backpack the rockies! In Colorado alone, you could spend 3 months. Flat tops, ouray, sand dunes, rocky mountain nat'l park, Aspen, San Juans etc. etc. But don't forget that Canada has Rockies, too. Jasper national park is high on my bucket list this summer.
