>>44945991Just merely having variety helps. The first four games basically just had boring caves. Unova up to Alola mix it up a bit with different settings like ruins, a giant mountain, and snow.
BW2's is probably the best but man it's long. Sinnoh's is the worst besides Johto's or Galar's lack of one. Sinnoh's requires a fuck ton of HMs, is extremely boring, and has dull music.
