I can strongly relate to this post for several reasons. First of all I'm absolutely agree about not having energy to play videogames as an adult, I mean... Using the same 100 + hours RPG you used: I can't allow myself to properly inmmerse in such compromise if I can only dedicate it like, 2 or 3 hours every now and then. I work a lot both inside and outside Hive, so when I play I try games with short campaigns. Second, I don't have children either, but even so I don't have too much free time, so... I feel you buddy.
I miss those gaming days, I remember dedicating thousands of hours to many RPGs.
Awesome post! :)
