This would be a unique feature that would set FE apart from other post ap mmo's currently in development.
Please read post in entirety before bashing..hehe.
I want player created environments that are instances spread over the lands. (Kind of think along lines of Warcraft (not WoW) and the player made maps on battle net.) Using the games graphics, engines, and pre-designed mobs, room themes etc, allow players to build dungeons that are playable by other people. With all the instances used in MMOs today, it can be done. (By dungeon, it could be referring to a fallout shelter, vault, cave, junkyard, abandoned office building, etc.) The players designing the dungeon are selecting floor layout, mob placement, mob levels, mob abilities (from pre set skill tables), attribute points, etc.. The loot tables are predetermined by the level/ mob type and NOT by the players developing the dungeon. Only one dungeon can be submitted per active account. Dungeons that receive high enough played counts & player ratings, could eventually make it to the hall of fame. (allowing that player to then create another dungeon)
You are sitting in town, with a group of people deciding where to go. You pick up the town's local paper or look at bulletin board to see the list of local options. Sort by average time spent in dungeon, kill death ratio, difficulty level, and PLAYER RATINGS to make your pick. Make your selection in town and get directions to the instance/ way point, and the instance can download while the player is running to the location. You go, you fight, you rate.
Maybe the designer gets some type of credits for the number of people his dungeon kills, he also gets bragging rights on his ratings, or making it to the hall of fame. There are a lot of options here of ways to reward the players for their creation..
A system like this allows for easily changing content (which also benefits future expansions) as well as allowing players to contribute to the world in which they immerse themselves in. The developers themselves can make some dungeons,(some premade ones will be needed to start off with anyway) and see how they rate in comparison to player made ones.
Other player created environments include player made towns, player made market places (EQ Tunnel Pre Luclin), alliances large enough to be considered factions of their own. The ability to shape the events round them, to contribute to the world, and to be a part of the world.
