just thought of this now, is it possible to Copy the entire world data of another save and paste it into another world?
like take some old gen world and port it over to an Arena save? or is this working into Save corruption territory?
I'm afraid I fail to understand exactly what you're trying to achieve, so the answer is hit-and-miss:
- You can copy your save, retire, and start in another mode, then revert to the original save, but I guess that's not what you want.
- Transplanting the history etc. from one geography to another would result in a mess, since some settlements would end up in the ocean, for instance. While it should be possible in principle by shifting settlements around, it would be very hard to do in practice.
- Keeping the geography and replacing it with a different history is easy: just keep the main seed and let DF randomize the other ones when generating a new world.
- Transplanting a fortress would likewise be a mess. The "easy" part would be to copy the site, but you'd also have to stitch the civ in, and its sites, and relation to other civs would have to be adjusted, etc. Likewise, the inhabitants would have to be adjusted, so Urist McTraderLover could not be friends with 15 traders from civs that only existed in the original world, etc. You also have regions, geo-regions, etc. to take into consideration, as well as instruments, dance forms, and so on that don't exist in the new world.
However, I suspect you're after something completely different...
