what engine was prey made on
First of all, it's not like we first do the game on console and then in the end we suddenly port the game to PC. It starts on PC. That's how game development works.. Another thing to note is that Dishonored 2 was developed on Arkane's own Void engine, while Prey was made using CryEngine 3. He went on to say that the number of different hardware configurations that developers have to consider for PC is huge.
