Bethesda Softworks offers fans of The Evil Within and Rage hope that follow-ups to one or both games are still possible (thanks VG247). Speaking with finder.com.au, Bethesda's Pete Hines tells them each game did well enough to warrant a sequel. This topic has come up before, in particular about Rage, id Software's 2011 first-person shooter. In 2013 Hines said whether a Rage sequel was coming was "TBD," and shortly after that Tim Willits stated that the franchise was "not dead." When asked about sequels to both games they say Hines didn't hesitate before saying yes. He expands on that in a follow-up answer:

Pete Hines: I can’t talk about the unannounced stuff and what we may or may not do. I get myself in trouble whenever I do that. Even when we were talking about the Morrowind Remaster, if I come out and say, ‘I just don’t think that is going to happen,’ then people freak out. So I won’t confirm or deny stuff we may or may not do, as people jump to the wrong conclusions. But I do think both The Evil Within and Rage did well enough that we could make sequels. Personally I loved Rage and had a tonne of fun playing it, but we have a lot of stuff in the pipeline right now so you will have to wait and see.
