Go to https://retroachievements.org/ for emulator. Check out games total players or https://www.vgchartz.com/gamedb/ for inspiration and dont hesitate to play long time classics for selected consoles, handhelds.

A gaming sub free from the hype and oversaturation of current releases, catering to gamers who wait at least 12 months after release to play a game. Whether it’s price, waiting for bugs/issues to be patched, DLC to be released, don’t meet the system requirements, or just haven’t had the time to keep up with the latest releases.
No memes please.
About being for bragging rights, sorry, didn’t mean you. Rather, to me it seems to be the common mentality, even if not usually worded like that. And for DRM, I consider as being as such because the player doesn’t control the content, even if it’s just a part of the whole package or a mod.
About integration of in-game achievements, solutions I see are usually lists or the sort in menu entries (e.g. Dust: An Elysian’s Tail where achievements are an entry in the start menu), or the addition of an extra area that doesn’t break the style of the game (e.g. FFVI T-Edition where the trophy room is added to the tutorial building). Also some in-game achievement screens can look rather nice, like (imo) FFXII’s.
As for a curated list, taking inspiration from a thread for GOG’s titles with in-game achievements, maybe either of us could make a similar one for emulated games here on the fediverse?
I just started such a curated list for ingame achievements for any game that can be emulated in RetroArch. Problem is, its currently empty. :D Who knows maybe I write a blog post someday if the list becomes long enough.
Retroarch on Linux, Windows 10+ and Xbox One afaik runs Final Fantasy XII for the PS2. And afaik, all PS2 versions have these achievements. And if you’d be willing to add mods, there’s also the aforementioned FFVI T-Edition.
Trying to remember any games or mods.
(Also poking about Wordpress having an ActivityPub plugin if you’d wish to include)
Looking at my notes, maybe these could also be included:
iirc it had achievements but also checking next.Main Menu > Extras > Clichés; I’d count since some can be rather challenging to unlock, and they’re just a list proving you did their conditions.Thanks for the list. For the moment I’m only interested into official licensed games for this topic. In the coming days I will probably dive into researching more to come up with something. I was thinking of Racing games, maybe sports or fighting games would be likely to have them. Or some classic collections with added bonus material and achievements. But ultimately, I don’t remember ANY game from the old days doing that. Your list is definitely a good starting point.
As for collections, I have two for the PS2, Atari Anthology and Sonic Mega Collection Plus. The Atari one I’d have to double check since I don’t remember, but the Sonic one has at least unlockable (often non-Sonic-related) games by hidden conditions, so maybe that’d count? Though the condition is pretty simple, open a certain game or games an X number of times.
Also just checked Dissidia 012 and Crisis Core. Dissidia 012 has an achievement system, Crisis Core doesn’t seem to have one.
For Dissidia 012, open the customizations menu with triangle with the character you want to check character-specific achievements, go to the right and open the first entry, Accomplishments.
