Iv been gaming since the early 90s so I am sure I have missed many games on my list.
These games are what's on top of my mind at the very moment. Ill go back as far as the N64/PS1 era Absolute gems in all catagories.

*No game is perfect* however if i had to give a 10/10 score, it will be these titles.

Horizon 3 is phenomenal, the best racing game  in years imo, and the reason I got an Xbox One. The game just doesn't get the attention it deserves.
