title: Libgdx networking for board game
body: <p>I'm writing a turn-based card game and I want to make it multiplayer.<br>
  I am a beginner on networking but after reading some articles, I decided I have to use TCP for my type of game. Furthermore, I don't know how to make a host-join lobby to play the game.<br>Should I use only libGDX networking classes, or use any other third-party library?
  If so, which should I use?</p>
