I want to play minecraft but all the servers these days have so many rules and those that don't are griefed regularly. I miss having my old private server that I rented which a few of my friends played on, they were all tended to earn their own way and then teamed up to start working towards the ender dragon which made that server a really enjoyable experience. Since they all stopped playing I haven't found any like-minded players so I tend not to play Minecraft
mc.hypixel.net is really cool. They have awesome minigames like VampireZ, Mega Walls, Walls, Quakecraft, Paintball, TnT games, and of course Blitz Survival Games. And soon they are going to add Arcade games (not sure what is in it yet). I play there a lot mainly Paintball. The Hive is also pretty good. I only go there to play hide n seek, but it's still a good server to have fun. If you are a survival guy, I don't know any good survival servers since I only play minigames now.
