Linux systems are usually laid bare for people to tinker with, which for me is specially good if I see something I don't like, be it software, UI or UX.
Plus, most PC's I've seen from at least the past ~20 years can run Linux, so if I get my hands on a working PC, Linux becomes an easy choice.
Plus², Linux can be made very privacy friendly.
On the plus side, this gives people plenty of time to tackle their ever increasing backlogs, and also to give companies more reasons to put out a functional product in order to compete with all the kilometric backlogs people already have.
Not a stats guy myself. At most, I get trophies out of something that feels a bit like OCD. Ultimately, I just want to have fun with my games, and not to boast them around. And tbh, one of the reasons I started dropping Steam was precisely the enforced social features (still use it, but now I'm finishing more games than I get instead).
You also need to find instructions specific to your device on how to unlock the bootloader, and a TWRP specific to your device. From there, you do a clean flash through TWRP (erasing certain partitions and then installing the new ROM), and then, you should be good to go.
Possibly older people and people with very specific use cases (like I did a few days ago).
One Piece, maybe? Pretty upbeat overall. Also One Punch Man.
I check sites that list hardware specs, and once I find a phone that seems interesting for an average price I'm willing to pay, I check places like XDA to know how much of a hassle it'll be to unlock the bootloader and add a custom ROM. And if modding the phone has too many/too big drawbacks, I return to the first step until I find a phone that seems good.
I'd suggest Linux Mint.
I don't mind necro as long as it isn't obvious spam, so don't worry. =D
(besides, Reddit also had a lot of this, where pertinent replies would only appear a long time after the posts were made)
But thanks! The game looks pretty interesting, going by the promotional materials, and the store page also mentions it has both English and Japanese, so likely at least texts will be translated.
On that matter, if you haven't dug on the topic yet and if I may suggest, look for Linux systems ("distros") with either the Xfce or Wayland desktop environments, since they're some of the lightest around (Xfce being the most stable of the two, but Wayland seems pretty promising already).
Besides GOG, which has been mentioned in other comments, there's also Zoom Platform (basically Good Old Games 2.0) and Project EGG {Japanese store/kinda preservation project (kinda since it uses some basic DRM) for games mainly from non-MS-DOS PCs}.
(Translated copypasta from the Portuguese community, yeah, but since not many English speakers understand Portuguese, worth doing)
Dunno the site, but one thing I do is to go to a site known as "AppSales" and to hide whatever titles I find with MTX with Ublock Origin filters. The process is a chore, but at least, each title needs to be hidden once and only once.
And sure, this is considering that the person uses only Google Play. I, for one, prefer to seek games in stores like Humble Bundle (owned by IGN), Itchio, and so on.
