I don't want a strong military (or rather spend resources researching one). Why can't I be Canada or Germany?
You can't be like Canada or Germany because the galaxy in GC isn't like the world today. Today europe and north america are pretty peaceful, and no one is worried about their neighbour carving chunks out of them if they don't keep up a strong defence. In GC the Galaxy is like the world from ~1500-1900 where a lot of the world (galaxy) has just become accessible and whoever gets there fastest with the mostest can claim territory and resources and might makes right. Worse still, there are activly hostile races like the Dregin out there, who will eat you given half a chance.
I just finished another game where I researched every diplomatic and influence item. The result? War with 2 of the "warrior" races.
Why not? Do you expect the ais to just sit about while you win a diplo or inf victory? Why would they do that? They don't want to lose. The ais are being smart here, you seem to want or expect them to be dumb and let you win.
I was successful in getting others to declare war on the first race to declare war on me. Then, after that race was finished, they came after me.
Ok, so the race that attacked you was powerful enough to hold you off while crushing another race? If you're that weak compared to them you will get attacked. Again you seem to expect the ai to just sit there and not use its crushing military advantage while you win by other means. Not gonna happen.
Even with my Max diplomacy and Influence, It would cast 40000 credits to get a peace treaty. What is the point?
It's because they know they're winning. If you were beating them, or even just holding them off for long enough you could get a peace treaty for a lot less. If you want to win by diplomacy you need to use it to avoid being in a situation like this. You need to be friendly with everyone and trading with the major powers. You need to use you diplomatic powers to forge alliaces and get others to gang up on any race pulling too far ahead. You also need to have a semi-decent military or ally with someone strong, because if you're a pushover someone will push you over and take your stuff.
As I see it, you are very limited in how you can play this game. You can win by Influence, BUT you better have a strong military. So you are forced to research military, planetary assault and planetary improvements from the start.
Well yes. If you only focus on one area of the game it's going to leave you weak in other areas and other races will exploit that.
So it would seem that I would have to play each game the same way (i.e. research the same items) every time. I'm sorry, but that is boring.
Not true at all. You do need to spread your focus a bit so there are some basic things you'll need to do every time, just like moving your pawns out of the way of the more powerful peices in chess. However, if you could do what you seem to want to, just focus all in one area, there would be even less varity and then it really would get boring as you'd just focus on the winning path every time and coast to victory.
In MOO, of course it was largely about war. However, I had to vary my playing style based on my race and the techs available. As I see it in this game, it really makes sense to research ground combat techs and go conquer.
Not really. I suppose on small maps you could just do that and rush everyone else, but on larger maps the other races would soon be out teching and/or outproducing you as well as out expanding you and possiblely ganging up to stop your warmongering.
