I have 4.5 mil, enough to buy that 6th treasure map piece which is like 3.5 mil. It's the only piece I need but I need to know if it's worth buying. Help?

its rarely worth it, but if you want to get in to the blue building then i'd suggest doing it now rather than later as the teasure map pieces have deflated.

Okay. What's in the blue building?

it's a secret, you have to complete all the requirements to see for yourelf

We aren't allowed to tell you that, it's part of the game that you find it out by yourself once you gain access to the Blue Building. C:
