Having GameGuru without this Building DLC is like having a hamburger without a beef patty.
Sure it can call itself a hamburger, but it's not; it's just a sandwich.
I have an ex-girlfriend who would go to McDonalds and actually say she wanted a Big Mac without the meat. WTH?!?
This is you without this DLC.

Don't be turning this into a "Vegetarians are people too" discussion, because they aren't.
People eat meat, fight, kill, lie, and have this DLC.

Think of this as your intervention.
I'm trying to help you, not hurt you.
Stop and imagine the shame of trying to explain why the game you are making has no building/s.
For the sake of your future mental health, atleast try to do the right thing by pressing the "Enter Giveaway" button.
