My preference is to start with the earliest of a series as a focus and supplement with some mention of sequels. That’s similar to how DGC has handled most series, “Pandora Directive” being one exception. Standout sequels could be worth visiting on their own. That said, WGC will be slower to cover games than DGC as there are only four per year.
Perhaps we could start with GTA3 and those more interested in sequels during the 95-XP era can join to detail those games on the call? Quarters are quite long, so it should be enough time for folks to try both GTA3 and Vice City.
