When was the last time you played an pure adventure game that immersed you in its world that wasnt an RPG/JRPG ? Even the action adventure are in the low numbers and from mainstain franchises only.
I call attention to jumanji movie (2017) part of the reason for its sucess is becouse the public is hungry for adventure movie, since we haven't had them since the 2000s with all those gritty and realistic dour action movies, games likely reflected this,who could forget the awfull period of glue to wall cover shooters ?.

Last one I played was The Walking Dead about 5 years ago, but before that it was Myst or a clone sometime in the '90s.

The adventure gendre seems to have died a long time ago as far as major titles go but there are plenty of indie options.

Assassins Creed, 4 Black Flag in particular. Awesome game. The others too, but 4/5 are really good at it.
Uncharted games aren’t on pc but I’d love to play them.
Would Dishonored not qualify? Tomb Raider?

Those are action adventure, not disqualifying them but they have more focus on action then the adventure part, hence why i separated them in my OP.
I would qualify dishonored as a stealth game honestly,sure you can hack slash, but like the reboot deus ex the focus of gameplay is stealth oriented,and based on your avatar i'm sure you would too .

I'm not sure what you would qualify as an adventure game in that case, can you give examples of your own definition? I would say Skyrim & Witcher 3 qualify as adventure, even though they have action as their solution mechanism. I would imagine an adventure game to have action as its main solution mechanism.

I think what's in short supply are real RPG's. Skyrim qualifies, but IMO Witcher does not. If you aren't developing your own character, how you want to, in the tradition of D&D or similar games, then it just isn't an RPG to me.

Adventure games dies out with 3d graphics.

We all recall the golden age of adventure games with games like:

- Adventure
- Zork I/II/III
- HHGTTG (best opening in a game every..)
- Planetfall/Stationfall
- Leather Goddess of Phobos
- Thieve's Guild
- Leasure Suite Larry
- Secret of Monkey Island
- Full Throttle

Leisure Suit Larry! Jeez that was back in the eighties before colour monitors. If you go back so far, how about Hack. A great platform type non-graphic game.

Hack was an action game, or prototype RPG.
