I know my way around a command line. I work in IT, but when it comes to my personal fun time more often than not I'm quite lazy. I use windows a lot because just plugging in anything or installing any game and it just working is great.
But support for windows 10 is ending and I should probably switch sonner rather than later, so I'm wondering if Arch would be a good pick for me? For reference, I mostly game and do Godot stuff in my free time.
If you have an interest in Arch, I'd recommend starting with a derivative distro like EndeavourOS. It'll give you an easy installation process and a desktop that's ready to use.
Then just use it as your daily driver. You'll eventually run into the occasional issue when package X or Y upgrades and breaks something, learn to fix that, and eventually learn the "ins and outs" of Arch. That's how I started, I went from Mint to Antergos, used that for a while, then when Antergos was discontinued (RIP) I converted my install to "pure" Arch and never looked back.
