Unless it is a race to space, I hope none of our games last long enough that we would need to sabotage space ship parts... 

Espionage seems pervasive, but it's not clear how important. GP tech preferences, on the other hand, won't impinge often but could be extremely important. Is there a thread somewhere providing that info?
I linked to the updated GP tech preferences on page two of this thread.
There are a few articles out there about Espionage, but I am going to write up an espionage primer as it pertains to the typical SGOTM and make it available to Xteamers when it's finished. That's great. Please PM me as soon as it's ready.
Thanks SCT, I look forward to it. I have noticed that without sufficient espionage points, you cannot see the AI graphs nor know what their empire's stats are. So it is important to maintain some level of espionage points and to manage them fairly wisely.There are a few articles out there about Espionage, but I am going to write up an espionage primer as it pertains to the typical SGOTM and make it available to Xteamers when it's finished.
This is absolutely true, and combined with the new bombard rules, has made me use Open Borders more to scout out AI territory and check on their unit defense levels. It also has made me plan more attack efficient routes to their cities and plan more precisely the contents of the attack stack. The faster you can get there with the right units, the easier it seems to be.However, now the AI will whip right down to pop1 if you have your units sitting next to their city. So there is big incentive to move in and take a city quickly to avoid all the extra whipped units.
JT, do you have a breakdown of which civs stack, which neglect defense, and which (if any) take a middle-of-the-road approach?
You eliminated Mansa Musa in turn 56!? Holy moley! We eliminated him in about 1500AD when he had a stack of Grenadiers in Timbuktu. You guys were on a different planet to us in this game...................
As I PM'ed,I just PMed all XTeamers a BTS Espionage primer. If you didn't get it, let me know.
