Can Pokemon Lose its Pokefun?

I bought Pokémon Y the day it was released alongside Pokémon X. I haven't kept up with the show in years, but I have consistently played the games out of habit and tradition. Besides, I do genuinely enjoy them.

The new game is awesome for many different reasons. We FINALLY have 3-D graphics and pokemon; not just "sprites." We FINALLY get some player customization. We FINALLY get to explore a new region with all the old pokemon we love and not just an overwhelming number of new species we know nothing about. Plus we got friend safaris, wonder trades, Mega Evolutions, and a whole lot of other goodies.

Trainers, breeders, and fans alike...I got bored.

As soon as I "completed" the game (aka I beat the elite four), I started training pokemon for a concept we had at school; The CSUF Pokémon League. We were to have a tournament, and the top five players would become our champion and elite four. If placed in the elite four, you were to have a team full of one type. I chose my favorite type, which is also one of the biggest challenges to train: Dragons.

I have my team, but I'm not exactly having fun. There's almost too much to put into a good, competitive team. EV's, IV's, sweepers vs tanks, physical vs defense, friendship, pokeamie....it all makes my head spin...

I guess my main concern is that maybe by putting all these different elements into the game we lose the essence of the fun, but maybe that's just me...
