This seems similar to some previous posts so, feel free to move it if it fits better there.
We know whatever Retro's working on is far along and, it's not unfathomable that it'll drop in 2017. Some people want Prime 4 (I do LOVE Metroid) or DKCR 3. But I am personally hoping for a new IP or (maybe more so) a Re-invention of a dormant one. Nintendo has dabbled a little in this regard to great success. Kid Icarus and Punch Out come to mind.
SO, what forgotten IP would you like Retro or another studio to Re-imagine? As the title states, I would like to see Retro tackle Startropics.
