I've got another one. Although this should really be a cautionary tale with the lesson being "know the mod you are playing".
Started a Legends of Revolutions (LoR) game, and got a killer start location. Stone to settle on, wet Corn, Clam, and Goldx2. Awesome, right? I got off to a fast start, and decided to build the Great Wall (I'm Stalin, I have Stone, and this was a large map, low sea level, and only 6 other AIs, so it made some sense).
Got the GW built, no problems. All the AIs are far away. Lots of barbs wandering around, but that's fine, because I have the GW. I spot a barbarian city just on the edge of the black unexplored lands. Take a look, and all it has are 3 Archers. Which are no threat, because they're Archers, and besides, I have the GW.
Except that this is LoR. 2 turns later, I get a "The Viking city state has emerged" message. That barb city is now a Viking city, so the GW won't hold them out. That's fine, because all they have are Archers.
Except that this is LoR, so the Viking Civ spawns a mini-stack of Chariots. Which is fine, because I have a Spear and 2 Axes in my capital. The AGG Spearman should make short work of them.
Except that this is LoR, and Chariots have a +50% against all Melee units, instead of +100% vs Axemen. So the Spearman goes from being an rock-solid counter against Chariots to a "pretty good" counter. But as the mini-stack of Chariots approaches, I realize that I can attack with my Axemen, since they have a 5-4 STR advantage over Chariots and the Chariot bonus only applies to attacks.
Except that this is LoR, and the Chariot +50% applies to both attacks and defense... AAAAND the Axeman is just 4 STR, not 5. So attacking with the Axemen is likely suicide.
And now it's too late to whip. I watched as my Spearman beat one Chariot, my 2 Axes lost to 2 other Chariots, and the Spear lost to the last Chariot. Buh-bye capital. I had 2 cities left, but Alt-F4'd regardless.
My next game will be K-Mod.
