How to structure 2D RPG?

Newbie & Debugging Questions
#1

My goal is to write a top-down 2D RPG(Similar to runescape classic, but much simpler) using LibGdx. My main question is how I should structure my game? I’ve made a previous thread asking about Component-Entity Systems and that seems like a good option, but I want to explore my choices.

I want to be able to have a few XML or Json files with most of the game content in it, and I could read all the data into my game and have it create the required game objects.

So back to my main question, how should I be structuring this game? I would really appreciate any help or advice anyone can give me.

Thanks.

I have allways used an entity-component-system. Even the famous Unity3D Engine uses this system, so i think it will be a good decision to stick with it :). Its relatively easy to maintain and makes the code look more structured. Of course others will maybe say something else, but thats my personal opinion :). You of course should choose which suits you best. A List of desing patterns in game developing can be found here:

  1. Take a pen and a piece of paper and write down your game requirements
  2. Do a quick brain storm about involved entities, objects, characters, level items, etc.
