None,
no one can do as good as the original,
leave the memory of something beautiful as it was,
and say goodbye.Let it go..
And firstly,you can only take over the game if you have permission.
Devs still keeps the rights to their games,you can't just take someone else's game and carry it on.
When devs make these game they instantly own the copyright to them.Basically means they can fuck over anyone who tries to take over their game and claim any and all earnings.
Granted the chances of happening are slim but who wants to risk it?
It's never just as easy as someone else taking over or more abandoned games would be revived.
And the guy that will continue the game need to know everything that the original author have planned,because great games have a writing that anticipate future,and the events that we guess through the dialogs and story need to happen.
And obviously,the story need to continue in the same direction.
He also need to know everything that the original author have defined regarding each character personality and past,
because we expect them to continue behaving like they did in the previous release.
And of course,he als need to have the same writing style,because it's not just the story that made us like the game,
it's also the way it's told and written.
And of course,this apply even more for the dialogs,the characters have to speaks as they always did until now.
Don't get me wrong,i fucking hate when a game is abandoned,
but you still can't steal other peoples work to use as your own !!
