I have spent many hours on Elder Kinds with my Mac, once forming the Tamrielic Empire.
You could make an 'extra challenging events' module, with said events that people can enable or disable at their option. I know in CivIV fall from heaven I'd always pop into the worldbuilder tool every 50 turns or so to give my enemies technology and units, or create a dragon/demon invasion force on the borders. Only thing that can mix things up when you get too big, while keeping early game playable, really.
That something you can't really avoid - unless we put in some hefty scripted events or rebellions. And people tend to really, really not like those.
If the thread is off-topic, that didn't start with me, no?![]()
But actually, can Mac users this mod? It looks like the only available installer is in .exe form.
