Have being deciding to upgrade my VIP status and when is the best time to upgrade. After monitoring for over a month, finally upgraded to Lvl 6 with during the Emerald dolls event (around 4.5 months after playing). Like to make a guess as to what I spend on to upgrade to lvl 6 ? (Hint : under USD25 ). Actually before spending any money on this game, I have ask myself one very important question :- will I regret spending it tomorrow, 6 months or 2 years later ?
