I played Neopets for a long time until they got rid of set spawn times in the shops and made it all random... at that point my whole money making scheme was ruined (trolling the magic shop until faeries pop, buy as many as you can for cheap, and sell them in your shop for overpriced amounts... I made over 1 million neopoints that way, but the problem with that game was they were pretty useless, not much to spend em on.
It used to be a lot more fun than it is now
