Some arcs strategy discussion

Hey, I've received my copy of arcs and we've enjoyed 2 games so far. We'll probably be using L&L in the next game.

I wanted to talk baisc strategy. How do you guys approach this game? It's so different then most games. Rather then just doing the actions you want from a list, you can only do what the cards allow. Much more of a "puzzle" to it then most war games.

A key thing I've noticed is I think the tyrant and warlord ambitions seem to be the best, if you can work towards those, they should be your priority. Your captives and your trophies can't be taken. We saw a bunch of times in our 2 games that some one would set up for one of the 3 resource ambitions (tycoon, keeper, empath) then declare it, only to be raided and have the other player score the points.

Do you find in your games that it's best to work towards the tyrant and the warlord?

What's your general strategy when you play? How do you approach the game?
