I'm only going to include genres that have a game in my top 50 or so overall games. If you can't place even that high as a genre to me I won't bother.

Puzzle - The Talos Principle
RPG - Gothic 2
Action - Dark Souls
Rhythm - DDR
Adventure - The Secret of Monkey Island
4X - Civilization
Tactical/Strategy - FFT
Sandbox - Yakuza 0
Stealth - Deus Ex
