Just picked up Ruby yesterday and I have to say this is the most fun I've ever had playing Pokemon. I've been playing since the start of the franchise and had a hard time getting through the Y because it finally began to feel repetitive. However. with the Pokenav mechanic implemented in Ruby, the game feels refreshing. As a kid, I always wanted to hunt for specific Pokemon and I wished the environmental battles weren't so random. Now that I can search for specific pokemon and compare abilities/move sets, it feels like a new game. Moreover, I enjoy "completing" an area by finding all the pokemon there are in a specific area. In my opinion, this mechanic takes out some of the guessing work of choosing a pokemon without taking away the novelty the franchise has created. All in all, I'm loving this game.
