Sorta a standard journey. We'll start out around Cerulean/Vermilion. We'll have one-two pokemon at first. The main plot of the story is to eventually stop Team Rocket, who will be doing evil things left and right. I kinda want it to be a suspenseful RP, where the good guys are trying to find out exactly what their friends are doing, some trying to help them get out of TR, some wanting vengeance/justice, and the bad guys constantly trying to keep their lies straight while satisfying Team Rocket and their friends. Like Breaking Bad in the beginning, when he actually cared about Skyler. 

As for Ralts/Meowstic...I'd say whatever's more common. I know Ralts is really rare in Ruby/Sapphire. And Meowstic looks cooler, but I'd have to be an Espurr for now.
