I have a 5-6 game rotation at any given time split between two groups:
Continuous plays - Destiny 2, Latest COD, FFXIV/Genshin Impact - these never leave the system as I play them between new releases or when new content is available within them.
New plays - Currently:: Deathloop, F.I.S.T and Kena - newer or recently released games that I may be juggling. something could be shifted to be backlog at anytime if a new title drops or I promote something from the backlog that I'm really interested in.
