TV: just don't buy an actual TV. Buy a monitor and hook it up to a Linux box with something like Kodi. You can hook up your cable box if you have that or stream from Netflix and such. Sure, even Netflix makes it hard as you can't get 5.1 surround but I'll take that and 2.0 -> 5.1 upmix over buying a Smart TV any day!
Games: Kerbal Space program sounds fun. Lots of mentions on HN. Apparently after some company bought them up changes of this sort have been made. So I decided against getting it even though I would probably very much enjoy playing it. Don't buy games like that. Buy games like Factorio or some GoG stuff (the ones that actually do work on your current Windows OS if that's what you use ... ;)) and do not buy into the GoG Galaxy thing. Get the installers. Otherwise that's like falling for Steam or Xbox Live or whatever the "Windows Live" BS is called nowadays.
Tablets and Phones: Use them for what they're good for: Making phone calls and browsing the web on the go. Apps are a curse, I avoid installing them as much as possible. Some exceptions prove the rule, like a free GPS tracker app for hiking created by a single guy. UI looks like it's out of the 90s but works for my use case. Found it because the other app I used started requiring a login even for the free part of the app. I refuse to bow to such things.
