I have found this achievement the hardest for me for Vegas. I had to form a small group of players to play each others slots daily just to creep along each day....in addition to daily begging. I have >2000 members in my mafia....and still it is a major feat. There has been so many new missions, now Italy, and et cetera that it has been difficult to catch folks attention to play. Currently, my tally is sitting at 536. 464 to go. Sigh. I feel the pain. Regarding Vegas, all else is complete. Yet, this achievement has been extremely slow to obtain. I hope that maybe by Christmas I may be able to finally get it. But, as before mentioned, I will have to continue and beg for plays and hope that my small group will continue to help. So far they have and I am grateful for them. But yes, it has been a very tough thing to accomplish with all the distractions.
