I've posted this in another thread, but I want to iterate it here as well.
If each kingdom had access to some type of EM tools, such as the EMs themselves do. And these events can only be joined (programatically) by the kingdom members that EM is in, then a kingdom leader can either himself or appoint someone to handle such things and then can create events more often for their members. The kingdom specific EMs could then have to compete in events dedicated to themselves to earn access to more event games. For instance a new kingdom EM might be only able to access musical chairs, but through EM events he/she can earn something like waterglass. This would also promote the hiring of kingdom EMs between the kingdoms, paying more for EMs who have a larger arsenal of games in their 'toolbox'.
Players would then base their kingdom choice on who keeps them busy with activities, not based on which kingdom is the 'coolest' or which kingdom has the most popular player who has the 'best' equipment that they might one day want to give away so everyone wants to be their buddy in hopes that they might get great stuff for free one day.
