I'm excited. LPB was a decent game. Not my cup of tea, but I enjoyed it for what it was.
Why am I excited? Because the social features of LPB2 were fucking FANTASTIC. Building levels and linking them, being able to comment, heart, favourite, put tags, but also go on their website, and do the same thing from their website. Queuing up levels and then hoping on LPB2 and the levels were there, ready for you to play.
That was really their first foray into the whole thing.
I truly am excited what we are going to see with the PS4 and their second go at it.
