>>24891880It really is Hoenn that gave the biggest abd most important changes, which is part of why I love it.
In my eyes it goes Gen 3, then Gen 4 (Phys/spec split), then Gen 2 (Breeding and held items), then Gen 6 (megas), then Gen 5.
On the other hand, there are miscellaneous changes that made games more fun - like shinies. Gen 2 was important for introducing them, Gen 4 was important for making them moderately available with the radar, Gen 5 was a shitshow (shiny locks? Fuck you gamefreak, why give us the shiny charm alongside shiny locks?) and Gen 6 has fair encounter rates without making them a complete joke. In regards to shiny pokemon, Gen 3 was the only gen that seemed to offer nothing (not even any guaranteed shinies like Gyarados.)
