I did Top 25 a while back... not sure it would be the same today. The list is pretty fluid. I love so many games, and usually I play just about every game in a particular series, so I'm just going to list SERIES, and then a few of my favorites from that series (note that most of my favorites are NES classics that turned into huge franchises):
Mega Man/Mega Man X (1-3, 6, 8-10, X1-4 are all money)
The Legend of Zelda (Zelda 1, Adventure of Link, Wind Waker, & Breath of the Wild are tops for me)
Final Fantasy (I, V, VI, VIII, XIII, & XV are my favorites)
Metroid (Original, Super, & Prime are my favorites)
Super Mario Bros (1, 3, World, & Galaxy are favorites)
...and Chrono Trigger to round out the list
