>>25260447Too many gen III Pokémon aren't seen if you don't have one yourself.
Shedinja, Chimecho and the Regis are almost impossible to obtain if you don't use a guide.
Altering Cave.
Lack of diversity on the surfing routes. Actually, overall there's a lack of diversity.
Almost no postgame in Ruby/Sapphire.
You need too many games to complete the Dex.
No other region mons in FRLG before you become Champion.
No Espeon/Umbreon in FRLG.
The games don't tell you what you need for the National Dex in FRLG.
Despite all this, I fucking love gen III.
