hey is there anyway to aquire the tenpenny house without blowing up meganton??

You cannot properly acquire it without blowing up Megaton. However if you go out to Tenpenny's balcony and walk around to the other side of the building I believe you can sneak it. You'd be squatting (the front door remains locked and you can't get room schemes) but I think you can still use it.

Yes, you can do what Hungry mentioned, but I don't think it would be worth it because you can't buy any themes or decorations for the suite. It's just a plain old boring room, hardly worthy of being called a penthouse suite.

You're going to have to live with your foolish decision!

Yeah... Y Y Y Y
