major inspiration: High Sea Caravansery 1 and Black Lagoon anime, however those are just base inspirations... i more or less simply add areas to the town atm, aras id like to visit, have a nice idea for another few locations yet...
as for factions, game mechanic wise there are alot of factions yet, merchants, citizens, pimps, mafia, pirates etc, but thats mostly just for interfaction reactions and ai behavior aswell as easiefied ownership issues
gameplay wise im atm having the mafia who owns the high ground on the island and runs the business, the pirates who raid (and still need a base), the citizens who live there peacefully
westernized arabian market... erm... lol... not sure if i see that

, i f you mean the word "caravansery", well thats not only arabic, that word was in use all over the silk road
should prolly add some markt stalls i guess

i usually build locations, add some base NPCs, add FX, add AI behavior stuff, add quests, finalize story... somin around those lines, but yeah story is atm the weak point still,
theres room for alot of story yet but i guess i might be busy worldbuilding for another month or so,
hence it would be very nice if i could get some nice and ready to use stories from anyone interested

mind that i dont really need somin like "the evil pirates want to overthrow the world", im looking for stories that are made like a story board, a script for a movie, dialogues, who talks to whom, what happens if that occurs and so on, details plz

, preferably in the way of a tree/branch graphic with arrows leading to new topics and so on
:) thx
