Nice guide. Some points that you might consider to change:
- Steam Punk, we had some discussion on this. I would not put it as a main theme. Post-apocalyptic is just fine (that's pretty much the overall consensus from previous discussion on that on this forum).
- Factions are there. The behavior is just not feature complete yet, I would say.
- In the Alpha part, you mention "earliest playable" thing. Kenshi was playable already in 2011 (ver. 0.2 if I remember correctly). So this is a bit a strange part.
- Also, the Beta part is strange as a whole.
Apart from my rambling, nice guide.
