Here is a matrix outlining the items that you need to purchase in order to finish each tier in Mafia Wars Moscow all three times. Special thanks to Don Scott for helping with the graphics (clicking will open image in new window):
M stands for Mafiya requirements, V stands for Vory requirements.
I am fairly sure this is accurate, but there is a chance there are one or two requirements missing. If you notice something is off, please post in the comments so that we can fix it. All item numbers indicate the amount needed to progress through the tier for the third time.
As a side note, the my guide, updated for Moscow, will be ready by the end of the week. Stay tuned (and be ready to check your e-mail to the people who submitted the post a few weeks back)!
