We have Mini Empires, Fortwars, Trench Wars and, well, you can really do almost anything in Blockland.
You want to build an industrial infrastructure and pretend it works because other games are too simple/restrictive to provide what you want?
Open up Blockland, think of a set of rules to go by, and start building like a madman. No restrictions.
Also, I've had plenty of hilarious/intriguing/historylesson/autistic conversations with people, because the playerbase is like a spiked mace that you can't get from any other blacksmith.
