>>36324521almost every shit you insint on saying has already been answered with the very first reply, i don't really know what to say without repeating myself over and over
>25% of the entire game's encountersi find it hard to believe when just in the caves alone have like other fifteen different pokemon, Zubats and Geodude are almost always more common than others but that's not really surprising and if it bothers you just put on repels
>does almost every single area have to be a cave?No that's why i already pointed out that there are much more areas to visit, outside of the obligatory Mt. Coronet and Victory Road the only other "big" caves are just Wayward and Iron Island
>brown/gray roomsyeah because that's what caves are you genius, Pokemon is fantasy but it never goes full fantasy (outside of the recent Ultra Space shit), most of the places you visit are just about what'd see in the real world, some towns, some grass routes with trees, some desert areas, a volcano etc. and only occasionally you get something more out of the ordinary like Chargestone Cave but that's always the expeption not the rule
Only thing i'd say though is that for being a cold region Sinnoh lacks a comfy ice cave
