title: Reversing Client and buiding a server from it
body: <p>I have this very old online game client (MMO) that has gone offline, and I want to make a server to this client.</p>
  
  <p>I saw a lot of this kind of servers like World of Warcraft private servers.</p>
  
  <p>I think that is not illegal do this to this with this client because the company is long gone, and I will not distribute...</p>
  
  <p>So, how do I start reversing this client to make a server? Do I need to capture the database requests and build a database based on the requests? I think that probably this go way further. Can you help me?</p>
  
  <p>Can you give some examples?</p>
  
  <p>Thanks everyone.</p>
