Those games you like and know will enjoy but still have not played because you are saving them for later or to be specific beast for last.
In my case its Witcher 3, DSIII, Deus Ex MD, Wasteland 2, Persona 5, Zelda BOTW.
And yes i played every other game and spiritual sequel or prequel in the series.
But somehow i constantly pick other games. Not necessarily bad games just games that i also like but probably not as much as the above mentioned.
Like recently iv bean playing more Atelier and Tales games.
Or games like Stix the gobo, Down of war 3 SP, The Surge, and Prey.
I did enjoy all of them thou.
