Look, I think Campaign is fantastic - but it can be a bit intense to try and get a handle on some of the functions as they’re way more manual than a lot of other platforms.
What you can ACHIEVE with it is amazing though - so I’ve pulled together some of my personal guides and notes and records around stuff that I find helpful for Campaign classic!
