I really want to do a modern world but if players want the normal fantasy world instead then OK, I'll do something.
But here are 2 ideas for a modern world I came up with:
1 - Basically the "Predators" movie. Throw the players on a jungle planet with other captive aliens and be hunted by Predator aliens. This idea seems more like a short term Mission world than a longer term world. But if players could build a fort some where and maintain it then it gives some longevity to it. But this idea would fit well the content of the modern worlds with all sorts of aliens and odd monsters plus mazes and traps and wrecks and ruins would all fit in the "story". But I realized this idea is very similar to the first Mission world, Raptor Island. This idea wouldn't require any programming but would need an active admin to add NPCs as players build shops for them.
2 - The entire map is.... a city! A 1000x1000 urban city with roads, sidewalks, buildings, sewers, subway system, etc. It would have plenty of land/houses/property to claim plus a lot unclaimable PLOT. Players then could demolish the land or keep it as is, whatever. NPC citizens would be present too. A lot of them, even setup with schedules like sleep in house, goto job, goto diner to eat then goto home to sleep, etc. Was thinking of creating an NPC economy of needs like food, clothing, etc that the NPCs use that way players can provide it for them. Would give a use for skills like Tailor, Carpentry (furniture), etc. The economy would be script driven using the global, saved script variables. So, if an NPC is alive, when the script is processed, it would reduce the food variable. Not sure what happens if NPC needs aren't met. Maybe they riot or die off or pillage players land, heh. I need to spend some time designing and fleshing out this idea. It would require programming for sure and I am willing to do it. Also, could attach floating maps that have wilderness for hunting, etc. The city would have plenty for combat: sewers, crime areas, events, special complexes (umbrella corp?), crime organizations, etc. Also thinking about implementing Prestige into this somehow so people can be good or outlaw.
OK, so just looking for some feedback.
