Í'm really excited about this mod! Sounds really good. When I have time I'll install it and give it a try. Especially the fact you have your own scenarios sounds great!
I've been looking for a list of scenarios, outof curiousity but also because I have some ideas for scenarios.
Not sure if something simmiliar is already in or planned, but how about a Peloponnesian war?
You could play as either Sparta, Athens or Persia. In all cases your goal is to control all of Greece.
Sparta should have a millitary advantage (recieve double experience for example), Athens should have a naval advantage (naval units may move after firing, pillaging doesn't cost movement points for naval units), Persia I'm not so sure about. Their true UA would actually do well.
The map would have all of greece, italy, but only a small part of current day turkey. This means Persia only has part of their empire on the map and they recieve some reinforcements on a regular basis (either units or gold).
Persia would start with the few cities it has on the map, these will however be fairly low on population and Greece will be largely unexplored for Persia.
Athens and Sparta will start with only their capital. All other Greek cities of any meaning are represented as CS. However, by allying them they become puppet cities of yours and you gain control over their armies. Still, the tribute bar remains and once they are no longer your ally they will go back to being CS and you lose control over the units again. You can also gain control of a CS by conquering them, in which case they also become puppets and you get their remaining army. All players will start with a few CS on friendly.
Since all spots of any use in Greece will be taken by CS, the only places left to settle will be colonies, either near Persia, in Italy or on the islands.
The game will revolve alot around allying CS, either by money or by conquest. This is the easiest way to grow your empire and millitary, although settling colonies will help you too. You can win either by taking all the greek cities, one way or the other, or taking out the other two capitals. This will not be easy since they will have a large millitary, since they are also allying and/or conquering CS to increase their power and army.
Alternatively, Persia could not be a player but a special CS, having several cities, and costing more gold to ally. But once allied it will send invasions to your enemy on a regular basis.
I think such a scenario could easily be made with both a realistic map and a random inland sea map (Athens should obviously have ocean bias).
Any good?
My finals are over today, I'll start modding again tomorrow.
