2, 6, 8, 12 is your box for a low-point, military strategy. Capital is wooded mountains. Perfect.
Plains are for fortress 1 & farming. Be low key. Build up all your resources under 50 points. Do not mind pillages. They are low military points scores for your opponents. In one 24 hour period I took an open field surrounding #8 province, switched capital well away from #8 and I am on my way to a Level 5 fortress in my new capital.
You can too.
But be a little patient (3-4 weeks build up)
