In this article it highlights and explains the importance of a core game loop. This article really helped me develop both my core game loops as it is directed at my games genre. 

Here are the key findings of this article: 

• The core game loop is just repeated sequence of actions that drives gameplay and allows progression  
• There are 4 key components of game loop; Goal, Action, Feedback, Progression 
• Goal – The motivator that drives the player and gives direction 
• Action – The tasks that involve combat, exploration, and puzzle solving, it is all dependent on the games genre 
• Feedback – The positive / negative responses to player actions 
• Progression – Unlocking levels, gaining abilities, the chance to face new challenges 
• In order to a well-designed core loop it must capture the players attention and immerse them through balancing challenge and reward 
• The example of a well-designed core loop was that of Apple Knight as it effectively balances progression, resource collection, and character upgrades to keep player engagement.
