LEGO

As a MOC builder, it doesn't matter to me what brand I use. I look at it as an art form as well, with the blocks being my medium. What's important is the final product, not what it's made with. Nobody cares whether Van Gogh used Faber-Castell paints or whatever.

When using non-lego pieces, I restrict myself to pieces that lego themselves also design, so I avoid specialised pieces. I think we both agree that using pieces that exist outside of lego's library of parts is "cheating" in a way.

But then again, lego themselves are making a lot of new parts which are made of other parts... Funnily enough, some of the new parts they're making, I could have sworn they were made by megabloks many years ago :) but that's a different rant for another time.
