>>29529521>arbitrary walls, uncontrollable elements and unexplained mechanicsI'm not sure what your talking about but it makes me suspect you're shilling.
The only "uncontrollable element" I can think of that was removed was the Game Corner, and you could just buy coins if you really wanted. The only unexplained mechanics I can think of are Sheen and the way feeding Pokéblocks to Pokémon at the Safari Zone affected them, which isn't necessary to capture them. And Granite Cave isn't an "arbitary wall," it's a dungeon. RPGs have dungeons, they make the game interesting by presenting relative difficulty via a need to endure wild and/or trainer encounters for a specific amount of time without easy retreat to a Pokémon Center. To say dungeons are arbitrary is to say Pokémon battles are arbitrary, and to subsequently remove a large number of trainers from routes so you can reach the next town more quickly.
