I have no idea. Looking at it just seems like another campaign DLC. I don't see a Steam Workshop to download any user made maps. Even if so I want to make sure it's a good / fun map. Clicking on a random map in game only generates flat, generic maps.
It's not a campaign DLC, it's a collection of however many standalone maps that afaik are huge and most of them are curated and polished community maps. People didn't like that, however, but that doesn't really speak to the quality of the maps themselves. Check out some reviews.
It's actually a collection of standalone maps all made by the same modder, Filthydelphia, who was later hired as an official scenario designer by the current AoE2 developer and has worked on a couple of DLC campaigns.
He made two or three new maps for this DLC, and polished up a whole lot of his older mods (mostly adding voice acting).
I like the concept of a DLC of standalone maps, like the "Historical Battles" campaigns from The Conquerors expansion and the first HD DLC (The Forgotten). But most of the scenarios in Victors and Vanquished didn't do much for me.
The majority of the scenarios here have a lot of scripting and unusual ways of getting resources, rather than the regular classic base building, which I'm not a fan of. They're also too large for their own good in many cases. And some of them have time limits, which I'm also not a fan of.
That said, there's a handful of good scenarios in here.
Otto the Great has you play as the Teutons in the early middle ages, with you being king Otto of the Holy Roman Empire. You have allies, but they can betray you if their loyalty falls too low. If their army is large they are more likely to rebel so you're encouraged to send them off to battle and grind their soldiers against the enemy. Your goal is to defeat Vikings, Magyars, and become king of Italy. There's also a West Francia faction (Franks) whom you have to pay tribute to or they'll become hostile. Very complex scenario, with plenty of varied enemies to fight, and classic base building. I liked that one a lot.
Oda Nobunaga is the most sandboxy scenario ever. It's set during the sengoku period of Japan and you can pick which faction you want to play as. Your goal is to defeat all enemy factions. Very replayable due to having different starting conditions based on who you play as, and every faction gets unique bonuses to units too so it's not just Japanese mirror matches. There's an achievement for winning this scenario on hard, which is a challenge because on hard this scenario has a time limit. I managed to get the achievement, but it was tough!
Charlemagne is another good one. You play as Charlemagne, have to make sure your brother dies so you inherit his lands, and then have to gain 100 "Imperial Score" which is gained through various actions, so it's quite the non-linear mission. You fight Saxons, Lombards, Ummayads, and Avars, so again a pretty varied set of enemies. Classic base building + conquest gameplay with the classic Franks civilization. Very enjoyable map.
Robert of Neustria is another Franks scenario with classic base building and some interesting twists. You have to usurp the throne, which you can do by either subjugating all dukes or getting them on your side by gaining their favor, which can be achieved through various actions. There's 5 dukes and usually you'll end up with a few on your side and a few as enemies. Some are rivals of each other so defeating one will gain you favor with another.
The other scenarios were mostly decent too, although a lot of them are too experimental for my taste. Still, the DLC is worth it for the scenarios I listed up there.
