PonyIsland.net (or .org) is an online site for people of all ages. You can breed, buy, sell, quest your ponies and more. The site doesn't restrain you to one breed, you have Unicorns, Pegasi, and many many more. It does cost money, but you can get a TRI (trial) account to start off which lasts for 20 days, but does restrict you from certain parts of the game. It costs $14 to play for 6 months, and $21 to play for a year.
While it is a fun and somewhat rewarding game, you will most certainly run into problems with the MODs of this site. It is filled with rude MODs (moderators) who enjoy the power of their title. The game has a very defined set of rules, and yet the MODs are allowed to break them and upset fellow players. They are very anal about the smallest of things and do not like to be told that they are wrong. They try to appear friendly, when behind it they are simply treating you like a child. This game has clubs that only MODs may join and know what they're about. The MODs also get special gifts and privileges.
I'm going to play PI. (I'm going to play PonyIsland)
I like to play PI, but the MODs harass me a lot..
I think I'm going to quit this game because the MODs treat me like poo and know they can get away with it.
Well, I brought up this problem to a MOD, and even though she's wrong, she's still being rude..
