>>7266389I don't keep up with Lego too much anymore, aside from checking out the aisles now and then. That being said, if you wanted a big lego city setup (like in the lego movie) I would think the City line would be a good place to start. They have a good assortment of different kinds of building that look pretty good, as well as things like fire trucks and other "utility" things. Get some road plates or build your own roads. If you want anything fancy like skyscrapers or irregular buildings, you'll have to buy the parts and make them yourself.
What I'd personally do/recommend is turn your basement into a large scale lego world with several different themes, so you're not limited to one or two lines. Have your major city setup and have those roads lead into cowboy world/christmas village world/whatever. Have a train station that leads to Hogwarts.A port that has a pirate ship in it. Do whatever sounds cool.
