@committed hero Attached please find a ToTPP "starter kit" with some caveats: 1. The blank rules I *believe* work but I made one set that was throwing up some errors and to correct them what I ended up doing was taking each section and pasting it into a normal rules file until I determined what caused the error. For the life of me I can't remember if this rules file is working or not. The most likely issue will be: NumberOfTerrainTypes, 16,11,11,11 I went ahead and changed the 16 to 11 and it fired right up so you should be good. 11 is the # for the base game. Up to 16 works but you need to have corresponding terrain 1, 3, 5, 7 that will accommodate it if it throws an error. These rules have the integer # for the units, advances, improvements, and wonders. This is important in case you decide to pursue lua, as lua can be integer reliant on events - i.e. it can search for unit 1 rather than engineers. (it can also be text reliant but I find that limits your options). I've included a copy of terrain 1 that works but is set up for Over the Reich and isn't from the standard game. I also included Over the Reich's rules just in case you coudn't get the ToTPP blank rules to fire. Hope this helps. Any special projects in mind?
