Coggle and gaming

I like coggle.

Its a GM's friend, especially if you are going to play with time or mess with prophecy.  A couple of points if you are unfamiliar with mind maps.

1.  They are non-linear.  It's a connection mesh of how different events will connect in your game.  That means you need to keep it updated game by game, but it will save you enormous amount of effort if you play with your timeline.

2.  You can rollback and make changes in your timeline easily but backtracking through your connected mesh.

3.  You can add plot lines and arcs to your games and show bits and pieces of the "future" through this method really easily.  Give the player a snapshot of the mindmpa so they can see the future through a distorted lens.  I usually provide a glimpse if they have limited powers.  Give them a pencil, paper and a minute or two to make notes all they want.  Someone with good prophecy power I would print out or send them an image of the mind map for the prophecy.
