I feel I must be missing something vital in what you are trying to say here. To me it reads a bit like this: “You have a great and unique concept here, but I wish the game would be much more like every other game.” I doubt this is what you really mean, but that is what is coming across.
We like that you post ideas, but we have to think hard about all effects those ideas would cause if we put them in the main game. If anyone can return to a previous city using the coordinates, this will indeed help with creating top civilisations, as has already been proved by the weekend event where we tried it out (Event 4 - Eternal Cities). But once you have an advanced city, the gameplay changes. You have “won” and any new babies being born will have no objectives to achieve. This game is about rebuilding civilisation - not about having a ready-made civilisation. In the weekend event this was easily solved, because once the weekend was over, so were those civilisations, and the game returned to its main objective.
I hope you see that the coordinate idea solves the problem you are thinking about (easier to create an advanced civilisation and playing with people you know IRL) at the cost of ruining the actual objective of the game (having to struggle together with strangers to take small steps towards civilisation, while never being sure that you yourself will be around anymore when it happens)?
You must have misunderstood something here. This forum has always been free. Maybe you are confusing it with the Family Chronicle feature?
Thanks for saying your piece. I hope this dispels some of the suspicions you voice around our motivations? Otherwise, feel free to ask more questions. And please continue to post your ideas on how to improve the game.
