Noob modding question

[Hiddlestom]

Hello everyone,

I'm new to the game and I was really intrigued by all the cool mods that have been done. I wanted to try a simple building mod where, to win, a faction needs to be the first to construct a certain type of building. Is this at all possible, making a building the victory condition? Like, each player needs to build a 'Monument to Victory' that has like 10 stages and if a player can build all 10 stages first they win. It's a bit of a mcguffin but I wanted to see if there's a way to program something other than a purely territorial expansion victory.

Thanks!
