Why yes, I have seen the Lego Movie. I couldn't wait any more to see it and can't wait to take my kids to see it.
I got to enjoy it on lots of levels, including the Lego FU hack. As players of Lego FU might know, I based that FU hack heavily on the Clutch Powers movie and the TT Games range. I was keen to see if there would be anything new about the ideas of Lego, or how "the Lego Universe" might work. Lego isn't something with a canon so I was open to something new.
But here's the thing about Lego. It's about recreation and re-creation. It's about building on what someone else already did. Even though Emmett is in a different world to Clutch Powers, or Batman, or the Hobbitt, or the Power Miners, etc., the same principles apply.
And what does that mean for Lego FU? It means you can play the Lego Movie with the existing Lego FU hack with only a teeny, tiny, difference for flavour. Running out of creation spark takes your minifig out of the game but makes them a minifig who always follows the instructions, including the overpriced coffee.
Now go and build your story! Lego FU is awesome!
