game options

[Admetos]

IIRC you can't change preferences mid-campaign. For that, you need RomeSage (I think that's what it's called) which is a save game editor which lets you changes all the options you choose at the start of campaign. I'm not sure where you could find this but I'm sure a search on the download section at TWC would probably turn something up.

load campaign, press ESC, game options, check "no time limit"
