I was unsure about this as I read the start of the article. The territories system allays most of my concerns though. It basically puts the onus on you to go and pro-actively defeat the worm that owns the territory before expanding into it.

If it had been the case where the worms can come and attack you wherever you are, I think that would have been a nightmare. Glad there seems to be a reasonable balance.

I love how they managed to make something that likely plays very differently from biters, requiring different strategies, but still keeping up with the same "bug" theme. It might be a work in progress but so far it looks exciting.
