Let's defin esome priority here:
1. I want (WANT!) to enjoy myself playing the game.
2. I like to be "in character", roleplay my part in the game.
3. I don't like to play badly on in an inefficent way to get the two previous points.
If my spies get a wiff of whe the Sakaturi really are it is the game that should point this out.
I still point out that the Ancient Guardians are much more a suspect than a few poor refugees.
If I declere war on them on sight I will easily win and that is bad for point 1.
But knowing at the player level who they are makes it really difficoult to roleplay correctly and this is bad for point 2.
Well, when I'm playing a 4X game "in character", I look upon it as "what's best for my race".
When they come out I'm usually well on my way to win (and I have already anything that I could 'want') so I think that I have done well for my race but for the point 1 P.O.V. the final percentage points to get to victory are usually the most boring. A good end of game galactic war against a worty adversary is good.
Given man's willingness to kill each other due to differences in skin colour, religious belief, political affilation and any number of excuses we've used historically, I figure that it's quite reasonable that questioning the morality of a conflict will factor into the political equation even less when one is eyeballing the resources that are being controlled by what one might see as nothing more than jumped-up cockroaches.
Point is that colony spamming brings more money and resources than war and as war is about money and resources the reason to do it is weak (even a little psycopath) at best.
All that I ask is a good war for good reasons: defending the galaxy from the bad guys is a good war, robbing a planet from a potential ally for resources that I can get by colonization or mining without problem is not.
That said I'm just telling that maybe colonization and mining is too simple and that maybe there are too resources. On the other hand we are speaking about a galaxy here, there are limits about how much you can resonably limit resources.
P.S. I have not yet looked out what weapons my ships are using. Design and war has been left to the AI(just dubled the warp engines for the colony ships at the start of the game). To win at DW that seems a little pointless.
P.P.S. The most difficult part of playing DW is answering the advisor 'suggestions'. The wrong click and you have started a poitless war or at the least lost valuable relation points.
P.P.P.S. I'm using too much the word point.
