Like those occasional illustrations in Alice in Wonderland or Narnia, game manuals provided a window into a world you couldn’t fully see (in the case of old consoles, due to low res or low poly graphics) and served as a jumping off point for so many children’s imaginations to fill in the rest of the details.

Wonder Boy 3: the Dragon’s Trap, a simple “Metroidvania” style platformer with fun action and enemy design. No deep story, but one of my all-time favorite game soundtracks

That games goes great with a real NES controller, so you can throw it across the room after dying.

Ultima Runes of Virtue 1 & 2 for the Game Boy. Great action-adventure-puzzle games. But very unforgiving, every dungeon is filled with fatal errors. I couldn’t get to the end when I was young!
