FishVille developer Zynga has released a “VIP Fish” feature into FishVille. This allows you to pay Sand Dollars to buy a seven day pass to be able to purchase an assortment of “VIP” Fish that yield greater amounts of coins and experience than just your average fishes.
If you want to reap the benefits of being able to purchase that fish again, you will have to buy another pass.
It’s definitely an interesting business move. It helps Zynga monetize their more rabid fans that want to level quicker–but you have to wonder if this might off-put some of their more casual users. It definitely gives a leg up to those that wants to shell out the Sand Cash to level up faster.
