>>58866198I think your issue is more "why do I keep seeing more challenge runs on youtube rather than normal playthroughs?"
"Why does nobody JUST play Pokemon anymore?" is just plain wrong. I can guarantee you much more people do normal playthroughs instead of challenges. The thing is that you might not see it because regular playthroughs don't generate that many views anymore (unless it's a fresh new game). Also, for older games, people can just experience it themselves by downloading the roms.
However, if they can't experience it by themselves because they lack time or skills for more "difficult" challenges (like soloing a game with a shitmon), they prefer to watch someone else do it, which is why those challenges get views.
At least that's how I see it.
