For music I tend to use Spotify’s similar artists feature or have the Youtube rabbit hole take me somewhere new. Sometimes I’ll even find new music from other media; like if I’m reading a fanfic and the author posts the song they were listening to when they wrote it, sometimes I check those out.
For books, it’s usually word of mouth, and for a games, a mix of that as well as reviews from people and a perusal through Steam Sales. I’m not too big on movies though, I just let my loved ones drag me into what they want to watch and they tend to have good taste. For TV shows, I let spontaneous mood choose for me.
Prince of Persia trilogy could work. It’s more linear than assassin’s creed so it could offer a change of pace.
