title: One table or more tables for entity with around 70 attributes
body: <p>I have a entity with around 70 attributes. It is about a battle in a game.
  Attacker have ships, while defender have ships and defense units.
  There are 10 different types of ships and 10 different types of defense units. There can be 0 or more ships and defense units of the same type.
  There are also 2 types of resources.</p>
  
  <p>So I need to have attribute for every type of attacker ship before and after battle, every type of defender ship before and after battle, every type of defender defense unit before and after battle and every type of resource before and after battle (total 64 attributes) + attributes like id_battle (AUTO_INCREMENT), date...</p>
  
  <p>Are there any problems with performance if table have 70 columns?
  Is there a better way to create this, maybe with more tables?</p>
