Yes...the new patch is kind of stirring things up a bit....I like it... Thinking along new lines and all that.... I find, though maybe it's still a bit early to be sure, that I don't mind attacking the AI if they've annoyed me....especially if they are close. It's going to happen anyway.... The "warmonger penalty" doesn't seem so bad now, though, again, maybe it's too early with this patch to tell....
I almost always accept DOF offers, and, if the civ is close...I also prepare for the eventual "Backstab".... In my current game Pachacuti is the the "runaway", has the strongest military, is several techs ahead, has built lots of wonders, has "trashed" all the other nearby civs and has attacked me quite vigorously, but I seem to be able to hold him off.... Hilltop cties and careful placement of citadels are critical in the early to mid-game...at least the way I tend to play...
My strategy will be to bide my time, and at some critical point make a mad dash for his wonder-filled capital which isn't too far away..... Maybe after Artillery... which is still about three techs away....
The AI still seem to throw everything at you in their attacks...and if you can soak it all up with careful "retreat/advance" tactics...melee in front and ranged behind... I think I should be able to grind him out...we'll see...
Oh yes...I like the new "pillage/heal" feature...you also want to totally kill off an attacking unit now so it won't pillage your tiles....before I used to try to systematically weaken all of the units...focussing first on the range units. Now I try to make sure I kill off attacking units...and try to make sure my city is in a good location and has walls, etc.... But, of course, it's all situational...they can only pillage a particular tile once...so if they are already weakened and are on a pillaged tile, I'll focus on some other unit...
