Fair.rewatched it just now. i think it looks great. on close inspection i saw at least 2 things that I don't think LBP3 could do so this might just be a from the ground up 3D platformer with LBP branding which actually would be pretty great for the franchise. so i think it looks great.
I had a different reaction, like lbp karting uncanny feeling, but I hope I'm wrong.
and for the record,.. lbp karting was a good game if you had the patience to wait for the stupidly long load times.
