Here are three things about the 90's I still don't care about-

31. I'm a 13-year Poke veteran,

but I agree that it gets tired sometimes, particularly when it comes to the game's formula. It is the 6th generation now, and they still are having players start using one of the same 3 types (fire, grass, and water). They still put the electric rodents in the games (Pikachu, Plusle, Minun, Pachirisu, Emolga, Dedenne), the generic rodents (Rattata, Zigzagoon, Sentret, Bidoof, etc.), more annoying bats and rock-type Pokemon appearing in caves, more weak bugs at the beginning (Caterpie, Weedle, Ledyba, Wurmple, Scatterbug), more early birds (Pidgey, Taillow, Hoothoot, Starly, etc.), the standard 8-badge quest, and a champion at the end that always includes some pseudo-legendary on their team (e.g. Dragonite, Metagross, Garchomp, etc.).
Another one of my main criticisms has to do with mega-evolutions. GameFreak only gave them to a handful of Pokemon--none of which are from the latest generation. And they basically gave them to a bunch of Pokemon that already had pretty high stats to begin with, such as Mewtwo and Tyranitar. I can think of a ton of Pokemon that have been in DIRE need of evolutions or stat boosts, but have seemingly been neglected. I would argue that GF played a bit of favoritism regarding which Pokemon get mega-evos, and gave them to many of the ones that are most popular with the fans. Even Charizard got 2 mega-evos, while Blastoise and Venusaur only got 1 each. And Mewtwo got 2, while Mew didn't get one at all.
