Guilds :
1-creating guild war arenas: to fight one player must use energy to acces the arena ( only to enter it) . The winning guild will win some points ( give a name to these points) and these points will be used when cumulated to create buildings and bonuses and more interface of a guild ( for exemple it will let the leader of the guild construct a PNJ market place in the guild, the market will be upgradable with more points and will be upgradable in 2 ways : either to pay less the buyable items, or to increase the number and quality of buyable items of this market). These guild wars will have different types of game , it can be a deathmatch or a catch the most coins rapidly without behing hit by the other team or it can be a football game any kind of minigame type war you can think of.
2- create special guild rouage where up to 20 ( for exemple just to mean a lot of people) are in the same map fighting a hord of monsters. You can even go more into the idea by creating only hordes of zombies wich drop random things that must be used to create guild buildings or expand the hall sizer which would lead to even more new buildings and types of war ect...
3-create a 2nd floor where people can put stuff there not using in some crates and other guild members will be able to take them.
4- create a 4th floor where only certain LIMITED high ranked members can go to recharge a bit faster there energy when they stay there even offline. just to be more precise there will therfor be limited high ranks and nonlimited ranks in the guild.
( to get more ideas about what minigames to create just ask me ;) I have 1000 good ideas minimum XD and its not exagerating)
Ps: Only the first 2 ideas are energy using ideas ( abotu the guild ideas)
Maps:
1- there is only one city this is a real SHAME. why not create other citys where the materials are differently gained ( exemple in the first principal city you have the rouage system or floor I dont know whats the name of this elevator system in english, in french it's " rouage" , and in the other citys you will have a job to accomplish , and another one where you gain drops from minigames ,ect...)
2-create simple minigames and hidden minigames in the game to give an explorer touch to this game .
3- create some energy using points to enter or exit a city ( but not to much energy so that people can swhitch citys easily)
4- create some kind of place between the citys where players have to go through to change citys and there are lotsa monsters. depending on the city your going to and if its a more noobish city or experience player city , the passage where there are lotsa monster will eb easier or harder to take and there will not let players with not enough experience go through. player will of course be able to get materials from these monster but a lot less then in the city.
Ps: evry ideas are energy using ideas exept the 4 because you alraidy have to use energy to exit the city and therefor get to these passage.
