Why do we feel the need to buy new games?

The human mind likes routine as much as experiencing new things. Actually routine becomes more desired with age.

Hence long running series have so much success, yearly sequels, DLC, GAAS.

Yet I assume you also keep buying new hardware and new games. Variety is the spice of life, routine is the anchor.

I do buy new games, I actually have a wall of physical games in my games room.
But StarCraft has been *the* game I always go back to once I have finished it.
