So this idea came to me when I was reminded of overwatch 2's announcement. At first the game seemed odd to me since overwatch is like a live service multiplayer game that still had plenty of room to be built on. But after thinking about it for a bit it actually makes plenty of sense. Overwatch has this reputation of it's poor balancing and toxic community and so a sequal can be a useful reset for the game. The player base have probably dwindled low enough to make economical sense to get a hopefully newer and bigger audience through a new game.
So I'm thinking this can be useful for Warframe too. I don't think "Warframe 2" is really going to work with all the progress people have in Warframe and how the narrative is built. So maybe a spiritual successor that's in the same or a similar genre to Warframe. DE has gained a lot of experience in game development from Warframe and to build a new game from ground up again can be incredible
