Yea XB1 mate,
Wouldn't have a clue who'd be getting it on PS4,
Editor is very different to what you'd be used to alright, you can't just stick stuff in there but the same in as much as it can be as simple or complex as you want it to be,
For the price mate you cant go wrong,

You can download free demos/trials of all the previous ones on PC if you need to check out gameplay and physics such if concerned about running in blind,
They're basically the same thing, but even at that this new one is the best I've played yet
