I had to cheat and put 26 games because I just couldn't decide on 25. But those are games that are on Playstation. Because this list is way too hard to decide if I also include Nintendo games like various Zelda and pokemon games and PC games like Star Wars: Knights of the old Republic ETC

ICO
Final Fantasy Tactics
Gran Turismo series
Suikoden series
Final Fantasy series on the PS1 and PS2
Way of the Samurai series
Silent Hill series

With the exception of Final Fantasy VI on the SNES, I feel like the above games are the foundation of my love for gaming. PC gaming added more later but it was this list that started things (plus others I'll probably remember later). That's why I treasure the PS1 and PS2 eras so much.

Goldeneye, Cuphead, and Breath Of The Wild, eh?

My top 25 PS games are within my top 50 games of all time so I can't list them all yet.

So far only 7 have been revealed:

42: Fallout 4 PS4
41: Disgaea 5 PS4
38: Uncharted 2 PS3
36: Dragon Quest XI PS4
33: Star Ocean til the end of time PS2
32: Persona 5 PS4
29: Bioshock PS3
