Compared to X & Y, Sun & Moon look like they will be a lot more enjoyable. It seems like there will be more filler (I guess?) in the game, rather than just beat all 8 gyms, get a bunch of Pokemon, and beat the Elite Four.
I'm not that far in yet though, so I'm unsure. It definitely looks promising to be the best of the two original titles for 3DS. I'm a huge Hoenn fan though, so I'm not even gonna include OR & AS in the mix.
As opposed to my normal liking to fire starters, I've started with Rowlet because I really like its final evolution. All these Hawaiian names are killing me though, I just kinda mumble the hard-to-read names in my head as they come up... Lol.
Anyone beat all the gyms yet?
