Well the project I'm working on it is called Italian wars. It features a historical period, so basically the story is already covered. You can see the first mission which is submitted here on hiveworkshop if you check my profile and the map is called Battle of Fornovo.
On the other side, I don't know if you remember, long time ago (when wc3sear.ch still existed), we were discussing about that MTG game Shandalar. Well, I found a version, I think unofficial, could be called a mod, which features additional cards, among them also multicolor and legend ones. The problem is that the guy stopped working on it so it may feel incomplete as you can see many cards from newer editions (yes 2001 could be called newer editions xD). I don't know if you are still into MTG, we could try this game once, if you're interested.
