CyberDanz - I can't speak for anything else in the mod, but I did make a set of Fallout resources for the mod, many of which were actually used in the mod. They are included in my publicly released resource collection, which is in my signature. Feel free to use any of that, all I ask is give credit to anything of mine you use.
I think every resource you specified are in that collection.
Good luck on your Mod. I love Fallout as much as Civ3 - the only 2 games I am fanatic about. I cannot spend much time in the way of modding outside of my own Modzilla mod, but I can certainly help you in the ideas department. I am very familiar with both Fallout and the mechanics of Civ3 modding...
Also - try researching some of the items you are looking for, such as the units. If the maker released them separately outside the mod, you can use them, but if they didn't you really should get Thorgrims approval first.
I'm Making a Fallout scenario for myself. I'm looking to make the map the whole of north america and maybe include factions from the more recent games. Is it ok if I use the resources in this mod in my mod? Unit graphics and terrain and that sort of thing. I most likely won't finish it and release it publicly. but if i do i will credit everyone whose resources i used.
Eamon - I made a collection of Fallout resources for this mod, some of which he used. Those are my creation, and I released them separately for anyone to use. The link to my whole resource collection which includes Fallout is in my sig. Feel free to use anything there as you wish, but if you do release something public, I just ask for credits on those.
As far as everything else that I did not make, I cannot speak to, only those creators can. Generally speaking Private mods are not an issue, but not necessarily always...
