There are way more freaks around the gaming communities than me, lol. I enjoy exploration a lot, it's one of the best things I love in open world games. The hardest map to fully explore was The Crew map, but had around 90% of exploration around it.
For games like The Division, Days Gone, RDR2, and so, there are many hidden, sub-stories to find, or let's say unspoken stories. One if the things you might find can be pretty unique, like in Assassin's Creed Rogue you find a photo of the first Ambassador (Omani) to the USA. Can't find it but was sent to me through Whatsapp years back, might search for it myself (it's the only AC game I didn't play due to not releasing on PS4).
