Too early to tell.
Personally I'm a big fan of open borders but it gets really confusing for new players.
We might have to design something that works for both sides.
Same story too early to tell.
Probably neither CF2 nor CF3
I think quite a lot of things will change especially the UI and such so we'll see where it goes.
We'll keep the community involved in decisions we make as much as possible.
We'll think about it if we wanna do something but we're not gonna transfer everything for sure that would just ruin the new game and make it unbalanced because it's probably gonna have a different currency system if it even has currency and so on...
It's too early to say but before the release we'll think about it and let everyone know about it.
If we make promises now we'll just regret it later.
No, the new game will have different (if any) currency it's not gonna work to move everything over.
We'll be restricted with the new game design and we won't be able to make the game great if we have to transfer all account data over.
