Assembly, it was my first faction that just really spoke to me, I really felt apart of the Assembly.
My favourite class in the Assembly is the engineer, from the design to the nostalgia, it has some amazing abilities too!
My favourite location is Nimbus station, a close second would probably be advent gardens, definitely some of my favourite music in the entire game in those worlds.
My favourite thing to do was get on and play with great friends. The community in Lego Universe was absolutely amazing.
