Bah its just a 3d version of Construct.
Really when you think about it all it does is a platform style, with limited textures.
it's still mostly 2d gameplay, but it doesn't just do platform games anymore, it can do topdown:
and first person/3rd person over the shoulder as well now (if you fake it ala construct):
you don't even have to make sackboy part of the games you create
also, I wouldn't be surprised if you could import your own textures files as stickers, that was a disabled feature in part 1. it's going to allow you to use your own sound recordings, so it wouldn't make sense to disable that again.
Not that the devs have a shared left nut... apparently hes gone for good.
aren't there at least two of them? or are you calling rich a shared left nut?....
