Ingress has that endless factor much like Pogo and Wizards. But it has more direct PVP with destruction of your opponents territory allowing you to build and defend portals (Pokestops) and create fields (tiny/super triangles). You choose a faction for life, Enlightened (green) or Resistance (blue). There is a badge system of keeping track of uniques, captures, building, deploying etc. And if you top out at level 16, you have the option of starting over "recursion" with all your experience and badges intact, but as far as the game is concerned, you're level one again. I've recursed four times. Most players never make it to 16. Pre-Covid there were scheduled events worldwide for group PVP and exploring the city of the hosting party. I attended these Anomalys / Mission Days in Vegas, Denver, Cheyenne, and Phoenix, with the pin swapping / swag buys etc. The median age of the players of this game? Us. Middle age and retireds. Clear as mud?
