I've recetly installed TATW 3.2 - so far I've only played several custom battles but I like it very much, apart from occasional CTD's I'm having in main menu.
I'd like to start a campaign as Gondor, for the classic "barely holding back hordes of Sauron" experience. From what I see, there's a ton of submods for TATW - which ones would you recommend to install for a challenging, desperate, grim Gondor campaign?
