I know that many of you play games on private servers. If you do, please post the name of the game here along with the link to the private server's homepage. Thanks in advance.
Generally, they're for games that you usually have to pay for... but on a private server you don't. Of course there are a few downsides. There's usually lots of lag, loads of bugs, parts of the game may be missing, no support, and it's totally illegal.
