Last.fm, even if it's not as used anymore, I still find very good recommendations there.
Spotify Discovery playlist has surprised me a lot in the past, but not that much lately. It suggests me what I was in the mood to listen to last week, maybe not that much today. The daily mixes are fine, but it's pushing the same songs too much.
Mausritter is a mix of some easy systems, very "kid friendly", it actually won some awards because of it.
The Tiny D6 systems are also good and easy to learn: two dice, if you have an attribute that helps, use three.
It depends on the amount of roleplay vs journaling you would like to try. My first try was with D100 and Four against the Darkness, but they were closer to a boardgame from my point of view.
After that I tried Scarlet Heroes, one of the best solo rules and tables to play any classic DND game. Or anything, the tables and oracles can be used in a lot of different games.
Now, the standard suggestion is Ironsworn because it's great and easy to play (although the book is big, everything is variations of one move). OH, did I mention it's free?
And then you can find Mythic GME 2ed, probably the best tool available to play any TTRPG solo. It's really worth it, but there are others easier to understand (I'd suggest One Page Solo Engine).
It depends on what you'd like to play: What setting? Where would you put the focus? More throwing dice? More journaling? Adventures? Epic fantasy? Sci-fi?
I started with no TTRPG experience at all around a year ago. There are some games (like D100 or Four Against Darkness) closer to a boardgame than an actual TTRPG. You throw dice and go with the results, no need to roleplay.
Regarding solo boardgames, I would say games where you play alone together, like each player doing it's own thing in the board with minimal interaction or minimal rules modifications. Spirit Island already mentioned is one great example, Cartographers, Sprawlopolis or Agropolis, Resist!, One deck dungeon... seriously, there is an amazing amount of options depending on your taste (deck building, throwing dice, etc.).
Of course not 😅 I'm not judging them at all, I finished years ago that phase where I thought my music taste what better than theirs now I just know it is /s
I linked it somewhere else in the thread. I'm finding there a lot of "new" stuff really interesting, even some of my favourites album are included here!
I still use last.fm, scrobbling pretty much everything I listen to from different platforms. The suggestions are usually spot on. Otherwise, the spotify radios related to specific groups or record labels help a lot too.
I see you are a man of culture. I'm not really into the thrash metal scene beyond some albums from Testament or Machine Head, but that album is amazing. What Rick Rubin achieved there was wonderful.
I'm doing something similar following this project https://1001albumsgenerator.com you don't need to register with an email, although it helps. A new album is suggested everyday, and even if they are not they kind of music you usually like, I am sure you will be able to appreciate why it was included in the list.
Amazing band, one of the best gigs I've gone to this year.
