Being a long time reader of Squidi.net's 300 hundred mechanics posts, many idea have sprung to mind following some of the ideas presented in the list. Some of these ideas following logical path from some of his ideas, building upon them, by adding piece of the banner games which he brought up as well.
This current post is simply in introduction to these ideas, bringing to light the basic premise of the ideas, passing by why one would wish to set up such a system into their games as a developer, and some of the possibilities which could come from this system. Within this series no technicalities will be discussed simply the general design/ideas behind such a system.
Before building such a system a fully functioning game would be needed, and I believe that this could be easily appended to a complete game with 'ease'(relatively, depending on he game itself, the genre and such). A web server used to connect to the banners and the game itself would also be required, for this system to function.
For this series, the person playing the full game and spreading around a banner will be called the Player, while the people viewing the banner will not be directly addressed, while the functionality of the banner will be described.
The player plays their game normally no matter how many banners are posted being used at once, or even if the player decides to not use this feature at all. The user would post the banners around the internet(Likely as part of their signature on forums, or something of the like), which would make anyone loading up the banner becoming a user.
To the player, the banner is a way of reaping rewards, for use in the main game, while for the developer, the banner is a simple way to get free advertisement. The player would spread it around to get the rewards, thus spreading the word about the game's existence, and potentially getting new players this way.
Many variants of this basic principle can be used depending on the game and the desire of the developers, for this reason this is where the Introduction to the topic will end. From here a few types will be discussed: First the Dungeon crawler game and it's possible banner, due to it's direct correlation to the original ideas discussed in the 300 mechanics project, followed by the use of such a banner system in a sim game, of the merchant/store game type.
