Hello Everybody,
This is my first post in this forum, so, my apologies if any of my questions have been answered already...
I have played FoG:Empires for 20 hours so far and do really enjoy it. Great game!
I have two questions:
1) Why is there no possibility to have the option to retreat if my army is attacked? Maybe I just want to lure a bigger enemy army into a terrain better suited for me or I just want to see my army fighting another day? I think this option should be available for the player and the AI, as it would provide for more strategic options.

2) If a building lowers decadence, does this apply only to the region where the building is constructed or does this reduction apply faction wide?

Thanks in advance for any replies!

1 - there is a minor variant of this, you'll sometimes see a message about patrols preventing a move,that is usually to avoid a too powerful army. But generally no, best to think of it as a period of manouver in a relatively large area but that sooner or later the 2 armies will need to fight

2 - the immediate application is to the region, so that region generates a bit less decadence, but for most purposes decadence is summed up across your faction, so the practical effect is to reduce it at the regional level and the global level

Thanks for the reply!
