Greetings one and all! I'm a new player, got the game a few weeks ago, and am thoroughly addicted already! Currently playing DA, and after a few easier / smaller games as the Terrans, I'm trying to move up to something bigger / harder as the Yor. And I'm currently getting my robotic posterior handed to me.

Here's how the game has progressed. I started in a corner of the map and think I did pretty good in the colony rush. However, very quickly I started getting messages from people who got paid to come kill me, and from then on I never had any periods of peace without someone trying to toast me. I held off for quite a while, but I'm quickly noticing that not only am I getting ganged up on non-stop by 2-3 races at a time, but the enemy fleets are getting much bigger and much stronger. As in frigates and battleship versus my small fighters. I fear my ultimate demise is nigh at hand.
Here's some of the basic stats of my game at week 185. For each race I'll list the number of colonies, population, total weekly income, and military ranking. Hopefully that will give you all a good idea of where things are at.
Yor (me): 14 colonies, 102 b population, 1324 bc/week, and 247 military.
Drath: 10 colonies, 71b pop, 1402 bc/week, and 64 military.
Thalan: 11 colonies, 98b pop, 2217 bc/week, and 939 military.
Iconain: 15 colonies, 104b pop, 1357 bc/week, and 413 military.
Terran: 11 colonies, 50b pop, 1193 bc/week, and 406 military.
Arcean: 9 colonies, 74b pop, 1189 bc/week, and 675 military.
Krynn: 6 colonies, 44b pop, 919 bc/week, and 117 military.
Drengin: 29 colonies, 171b pop, 3675 bc/week, and 1923 military (OUCH!!)
Altarian: 23 colonies, 114b pop, 2032 bc/week, 681 military.
Korx: 6 colonies, 47b pop, 559 bc/week, and 271 military.
So I'm clearly not the weakest race of the lot, but given that the Drengin, Arceans, and Iconians currently want to kill me and all but the Arceans are next-door neighbors, I think death is inevitable. I'm close to getting Psyonic Beams, but I doubt I'll have enough time to build up a decent enough fleet to hold off any invasions, and it will take all my resources to do so leaving me even further behind in development.
So where did I go wrong? What should I do differently? Are some games just bad from the get-go based on the luck of where you start and what planets are nearby?
Speaking of planets, here's the approach I've used in developing them. I've read tons of posts and strategy guides, and have been trying to use the specialize approach. Low PQ's are all research, things in the 9-12 range and generally manufacturing, and higher than that are economic. What I've currently got after the first round of terraforming are 5 research planets (PQ's 5, 5, 7, 8, 8); Manufacturing planets total of 4 (PQ's of 9, 10, 11, and 12); and 3 economic planets (PQ's of 11, 11, 12, and 20). I also conquered two minor races (PQ's 15 and 16) whose planets haven't been rebuilt to be specialized, but are currently a pretty even mix of everything.
So how's my ratio? I'm currently thinking that I should have done more manufacturing. From scanning though enemy planets, it looks like the AI rarely uses econ building except on higher PQ planets, and puts lots of factories on pretty much everything. I've also noticed that the AI sometimes puts a fusion generator with no other factories. Does that make any sense to do?
As far as getting ganged up on all the time, are there any tips of strategies to make people not want to kill you? Is it because I'm EVIL that they are more willing to kill me?
I realize that there are a ton of questions in there, so thanks in advance to any tid-bits, tips, or pointers that anyone might have to share.
Cheers!
