Retrodeck in your case then if you just want a simple setup.

Cool devices, but I've seen Beelink PCs with better specs and for cheaper. Cool if you want the case but not really worth it at the end of the day.
This game is actually amazing. Me and my friends play it almost daily. It is crazy how crazy the quality is for being a free open source game.
PC support is around the corner too so that probably has an effect too.
Only works if you haven't updated it since the February 2021 update. You also would lose the actual built in Chromecast feature.
Cool but I don't really see why you would do it on this device when you can just flash android to a raspberry pi or something and have basically the same thing at that point.
Summer sale is June 27th. I would expect it to go on sale then. You can also keep an eye on deal.gg and see if you can get a key elsewhere. Buy at your own risk though as most of the sites on there are key resellers with unknown origin how they got them.
If your looking for a f2p game similar to this just play Beyond All Reason.
Free and open source. No energy system or microtransactions.
Not asynchronous though.
If you sideload VLC yes. I don't believe it's on the official app store.
There's a docker image called wg-easy I use with a nice web interface.
A lot of the modern arm chips are 64 bit now fortunately. Not sure about RISC.
Based on the hardware you have, if you're able to install it on one of the routers, I know that OpenWRT can set DNS on a per device basis with it's DHCP server.
My personal suggestion is to use a PFSense device as there is an option for per device DNS settings, along with a lot of other options that you might want to mess with if your trying to learn some networking
Unfortunate but not unexpected. We're probably going to see this more the further we get from cross gen console games.
