Guild Wars 2

Maybe you should also give the chance to the community to actually let them program npcs, for example make scripts for self contained bosses in built guild castles, which could be challenged by other guilds. Also if you could come up with a real in game modding api, where people could allocate a certain virtual area, where they could put and program what ever they’d like to, so every guild should have their very own unique gaming ideas what others could try out. Or imagine a guild wars 2 where players define what is gonna happen to the environment, like moving guild castles with ghosts swarming the place where they go, or a dragon guild who hatches dragons to fight for their heir, or players riding giants into battle to swarm the all mighty capital cities. Let players to be the evil of the game, as how they want to define it. You could make this to the shop also, like adding modding features for also gold and diamonds into the shop, for example, you could buy an npc for x gold and an npc programming kit for another x gold while binding the two together would make out for something, so this would actually make people to work together to make something fantastic, unique in an always changing and interesting world.

Also it would be awesome to have a game mode where you can be whatever character you’d like to be by the press of a button preprogrammed, so people could show off their skills in knowing all the characters in a pvp fight. (Like for example i preprogram to be a warrior with such and such skills on button press 1, and i preprogram to be a necro button press 2.

2v2 arena ladder would be really really awesome (since 5v5 is such a mess and barely professional, there is no real room for making real tactical decisions and reactive gameplay to take place, you just get carried away by the flow of particle spam and such)
