I'm gonna repost some of this concept from another topic. because... well I can. :P
I'll explain my easier way that 3D-Roaming could be added into LBP3 without the company having to change the heart & core of the game. And it is user friendly to new players too, Which is important because the last thing LBP needs is to be even more crazy complex. LBP should always stay as simple & easy to use as possible as to not scare off new creators & players but still at the same time adds new content that's useful to everyone. I tried to explain this concept before, but I never did it in enough detail until now. *mew
Anyways What I think will/should be added to LBP3 will be a option to allow Sackfolk to walk on the front of walls topdown style, which would be a powerup or a logic thingy. And when this is combine with a camera logic set to a fully working 3D view,
(Which also should be added.) With all of that, We will get a actually quite nice and simple way to create 3D roaming levels without changing the core LBP game engine. it may be more limited then people would like. but they really shouldn't complain at that point since it still allows for a lot when done right.

And if combine with the extra layers that are for extra-visuals-only the company may also add, you'll get a pretty fancy looking 3D roaming level overall.
I would also think that Topdown-Sack will be able to jump one layer high. And when it touches a hazard surface below it's feet it'll die. And it'll also be able to still grab objects. *mew
Keep in mind that this concept is only for a LBP3 if it is made for PS3. not PS4.
PS: Again, I won't bother replying to anyone who disagrees with/dislikes my concepts here. I have better things in life to do. Haha~ xD
