RP is RP. Whatever you want it to be. Use your imagination. Some people have an entire history in their head, and just use that as their basis, others come here and add little bits here and there until they think they're good. Resources you can pick to suit where you're placed on the map, which can be anywhere left (black space). You can ask for any design you want, though Oz adds his own details, most of the time. And... sometimes people make their own map and post it, so... it really doesn't matter. Citizens is controlled by your NS country, though Oz has said that RPers should reduce by 1/6th, like he has, but... Oz is huge, so... moving on. Flags... I know you PMed Tweedy, but I-S can make flags too in his RP shop. Just in case you wanted another option.
Your friendly RPer,
Talmann
