@Zitacamron95I totally understand! I caught the stomach flu, so I haven't been on in a little over a week. No worries!
Mauville City would be perfect - it's considered a central hub for travelers, which makes it a good place for the professor to hold an audience.
We could place this after Team Aqua and Team Magma; in the wake of their collapse, there could be small groups trying to rise, but ultimately no major conflict from them. Just something that might cause trouble on the road or in towns, whether directly or indirectly, but leaving the primary focus on slice-of-life. Not really any "Team [Blank]" or anything, just criminals that could be stealing Pokémon, and/or research data. Relevant to what our trainers will be doing, but not taking center stage.
I like having the roleplay largely slice-of-life focused, though. Personally, I just like to see a little conflict from outside sources, but like I said - it wouldn't be the focus, just a few things here and there that they experience or hear about.
