I've found Marathon mode to be pointless. Sure, there are more turns, but it takes twice as long to build anything, so you just end up spending more real time without actually getting more done in the game. I've been very disappointed with Marathon.
Because I haven't found any mod to fix this for BTS, I decided to take a look at the files and see what I could do. The result is an extremely simple 'mod' that turned out to work well for me. I had some awesome drawn-out conflicts with ancient units. You can really pump out those soldiers, but so can the AI of course! So if you decide to use this, you better keep a big army, or you'll have big stacks knocking on (down) your door
So again, this is a very simple adjustment attempt to get a real marathon speed instead of the meaningless one that comes with the game. It has no guarantees and I'm sure real modders would laugh at it. I won't even put it in its own thread. But it worked great for me, tech times seemed to fit and all aspects of the game worked well. The only thing might be that in the very beginning you'll wait a bit until you have the basic techs for workers etc. You'll have ample chance to churn out units and wage some serious war.
