I'm not really sure if I like these browser games where you have to spend a lot of money to get items. They don't appear to be good value to me and well, a bit pointless when you have to spend £8 to expand your zoo, etc. If the number of diamonds of things were less, or you got more diamonds for your money (or what ever the 'premium' currency in a game is) then I'd be more inclined to, but not now. Plus, I always have an aversion to spending money on something which isn't a physical object when it comes to recreational purposes. Seems daft.
