Ghost Manor for the 2600 is a fun game with lots of atmosphere. However it’s also pretty simple and will only occupy you for 10-20 minutes. It sure was a blast when I was a little kid, though.

There’s also Monster Bash, the 1982 Sega arcade game.

Ocarina of Time. After the action and increasingly beautiful pixel art of the first four Zelda games, I found the 3D one boring and ugly.

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

I’m with you; I like the Metro style. If you have an Android phone, the Square Home launcher is a great implementation.
