I recently acquired Mario Kart 8 Deluxe (I only recently got a switch) and the couple of F-Zero tracks there have made me wish for a game of this series to come out. Pleaaase

To be honest you can get Cave Story for free already since it's open source and in many distro repos. Also I think the publishers kinda ripped off the original creator so the guy who actually put the work making this masterpiece isn't getting anything

Solving the Rubik's cube

You either get into speedcubing and get high end cubes to improve your performance, at least of the official categories and a couple must haves like the Mirror cube.

And / Or

You start collecting cubes and puzzles of all kinds and shapes (yes, even non-cubical :o). You start to acquire custom cubes built by hand by artesians or niche brands.

For the love of what's good in this world, stick to that one budget MJC set of competitive cubes until you are actually 10 or 20 seconds behind the world record

I completely disagree, the device feels really sturdy, I own both a PSP and a Switch and if you ask me I think the switch is more flimsy. The only thing that ages the PSP imo is the UMD reader and the lack of a second joystick, but I still love the design today

Well, it is a proprietary format after all

Unless you already have it, to be honest

Stick to local stuff, no need to open ports at all. I got myself a Raspberry Pi and I just have it next to my router.

Once I felt like using it outside my network, instead of opening ports and doing complicated stuff that didn't work cuz I am behind a Nat, I just used Tailscale instead, it's a private VPN that is free for a limited amount of devices (like 10 or more I think so it's fine for you and family). It's the best easiest thing ever

The Xiaomi Poco F5 Pro, its bootloader can be unlocked and it's fairly powerful. I am sure a good rooting and modding community will come out of it.

However, the unlocking process can take a couple weeks which is not great, also MIUI by default sucks.

The Pixel line is always pretty good for custom roms and stuff

I quite like using K-9 Mail, it merged with Thunderbird and great things are coming for it, I think it's awesome

Well you can install it locally and get the web interface via localhost, but if it's a proper server you can access the news from your sources from anywhere and you can also use 3rd party apps in your phone to get a different interface via the API

FreshRSS, news and websites fetched your way. You can even create feeds for websites that don't provide one
