No problem man, im kinda busy myself, so I cant answer each day either. hmmm with a good story. Pokémon Full moon, the game I was playing earlier, had a decent story. only up to 6 gyms now, so maybe wait until next update before playing that.
I am now playing insurgence, I was told that one has a great story. Pokémon Reborn has an interesting story, but the level curve and the overal difficulty kinda distracts you from the story, so I wont recommend you that one.
Insurgence is interesting, so you can check that one out if you like it. Have a nice day!
