I like to keep track of my games that I have completed, with most of the games it is pretty easy. When the credits roll, I consider them beat, there are a few exceptions of course like Nier, Resident Evil 2 etc. What I struggle with are fighting, racing games and 4x games. I enjoy these genres, but I don’t know what is “satisfactory” amount that would make me think that I played these games to completion.
Some examples:
- Guilty Gear Strive (or any fighting games that are not Mortal Kombat, injustice or SF6)
- Civilization 6
- Project Cars
Typically, for any game that has a campaign, I would consider completing that completing the game.
That doesn’t mean you can’t continue to have fun in endless modes or multiplayer. That’s a different orientation.
For multiplayer games, there’s no completion really. Play the tutorial? All maps once? Win once? Ranks? Endless leveling progress? All achievements? None of those really fit. There is no completion to a game without designed, completable progress. If there’s a max level, one could consider that a kind of completion. All achievements may subjectively fit too.
