This is a tentative design doc (TDD) providing a list of aspects of the game. It also collects suggestions made in these forums.
***
Game Aspects and relevant suggestions are collected under appropriate headers.
The TDD will be updated as aspects become cleared and suggestion come in.
Please also suggest how to organize this better, i.e better header structure, re-placement of suggestions under other headers etc... Also Hoehrer and Mattns feedback is needed in order to clear what will be adopted as official feature.
Please report any necessary corrections regarding factual things like for example already implemented features still being kept under "Planned" or inapproved ones still being kept.
It is highly appreciated if you contribute with diagrammes that visualize relations or flow of mechanics etc.
