Checkmarks for finished games ?

[XeLo8]

Hello, yesterday i my mm+ finally arrived and i started playing something opened atari2600 and played adventure... enjoyed it and finished it... wanted to move on other game but i would really like some kind of checkmark or at least something like
A̶d̶v̶e̶n̶t̶u̶r̶e̶ Adventure ✔
Example Example X
Example Example X
Example Example X
OR which sounded like most natural way to implement this is currently in front of every game i have - so

-adventure +adventure
-platform -platform
-puzzle -puzzle
-example if i played them and it would show +example
