Would a Mass Effect TV series retell the story of the games or a new story.
The timing could work out, though, as publisher EA and developer BioWare (which is owned by EA) are in the relatively early stages of developing the first new Mass Effect game since 2017's Mass Effect: Andromeda.Andromeda saw a lukewarm reception (though some people liked it), so it's been a while since Mass Effect has been an IP to be reckoned with.
