I dont have one yet.
That was part of why I laid out a post for each step of it. I created the "Scenarios, Maps and Mods" forum and have always regretted the small number of scenarios compared to Dom2.
Ive done fancy shortcuts, preexec, postexec, and maps. I dabbled abit in mods and was fascinated at the information that they could be changed in mid-game. Ive written many scripts which modify any and all of the above.
I had various notes about how they could all be tied in together but nothing that jumped up and screamed to be done. At least, not that I felt in my power. Of them all, MOD is my weakest so anything extensively built around the mod part I will be happy just to have spurred someone else to create it for us. Even if they use the whole scenario package idea, I would have no problem with that.
I was hoping for some other ideas in each of the various pieces about what would be impressive "if it could be done". Thats one of my favorite subjects "if it could be done".
