Hello everyone,
I'm really glad to have discovered this new mod, and I'm quite impressed by your work! But if you CAN'T waste all this beauty on the vanilla M2TW! Really, it would be a crime!
Why don't you look for an expanded map, maybe from a released mod (I would suggest The Sicilian Vespers), and ask the modder to use it? I'm sure it won't be difficult... And why don't inculde an AI mod, you know, Lusted Experimental AI, XAI 2.20, Ultimate AI? They all work fine, and their creators loves to give them to anyone (I guess there's some kind of competition between them...).
I know that maybe you would prefer to build your own mod (all by myself... ta-da, ta-da, ta-daaaa), but while you're working on, go fisching in the modding community and make your first relase great! You know, the players got used to a wider landscape of regions and to a less stupid (I can't say more intelligent) AI... the vanilla is outdated. Think on it.
Best wishes - you're doing something great!
