Combine different game worlds and characters

March 15, 2017 57 views

There is a lot of open source games out there. Each one has its own world and character created. Usually they are created over different game engines too (unity or unreal, etc...). I am wondering if it is possible to do some coding to combine these worlds that were created by different developer? If not possible on the worlds that were created over different engine, what about worlds created over the same game engine?
And if worlds can be combined, what about the character? can independently created character travel through different worlds?
