The key when it comes to not getting bored with computers is to work with something else!
When I was in "the business" I often felt that I did not want to see a computer when I got home, now when I work in a different field thats not the case at all 😀. I still find new computers lackluster though as I like to tinker, changing CPU multiplier and setting a video cards "power envelope" to 120% sadly doesn't do it for me. I still love my EVGA SR-2 system as its the total opposite, making two CPUs play nicely at the edge of stability with endless tweaking settings is my understanding of a fun time!
When it comes to retro stuff its not only nostalgia for me, its more about the challenge. My first PC was an IBM 386SX but now I'm having a blast tinkering with a 286 system. For me its just as fun if not even more so to muck about with hardware I never tested before. I have no other goal with my tinkering than to see what will happen if I do this or that.
I like playing old and new games but I spend perhaps 10% of the time playing and 90% of the time messing with the hardware. I used to play World of Warcraft in hardcore guilds from the release until 2010, during that time I played a lot, but only WoW 😜. I doubt another game will beat the rush of being the first guild on the server and sometimes one of the first in Europe to clear a new raid instance. Gaming has not really been the same for me after WoW.
