reallyworld

reallyworld runs at zeny.reallyworld.ru and it's a straightforward Minecraft server to drop into if you're already familiar with the game. It doesn't dress itself up with a fancy pitch, just an address you can plug straight into your client. If you want a refresher on what Minecraft itself is about before you connect, the Wikipedia page linked on the listing covers the basics. Worth a look if you're hunting for another world to add to your server list.
