>>38019320Random encounters and Overworld encounters are both slow as shit because all battles in Pokemon take fucking forever to start compared to other RPG franchises.
Overworld encounters could be done well, but not with the way Game Freak designs maps. They're just way too fucking cramped for Overworld encounters to look good or even work well at all, and LGPE is pretty much proof of that (See: The video of the guy who sees a Shiny Ponyta and walks right into a Rattata that was standing in front of it.).
If Game Freak could actually design Overworlds that lent themselves well to overworld encounters, then sure, they could work. But as of right now they've proven they can't, and because of that Random Encounters work better for the time being.
