I've found I tend to care less about things now that I'm, frankly, a bit older and worn down by the family life. The effort of chasing quality or completion (of say a discography, or ROM set for example) has given way to the convenience of 'good enough'. I can tell the difference between the lower quality and the higher quality, but the lower quality in general, will do for me.
For instance, I used to care about music and use relatively decent speakers and all that but now I'm just far less fussy, and I'll even pay for a spotify subscription for the convenience and use a bluetooth speaker or the telly. Also, the Wii looks pretty shit on a 4K 50inch screen but it's still fun. The TV isn't top spec but it's watchable. My car's a bit shit, that's OK it still gets me where I need to go.
The only think I'd say that I can think of right now, that's gone the other way, is that I try and dress a bit better, buying nicer fitting and styled clothes, less band t-shirts and sloppy fit jeans.
