What makes a game mode?

[Vitatroll]

At risk of bloating the topic:

Normal gameplay:

• Nuclear Emergency
  
• Traitor
  
• Changeling
  
• Wizard
  
• Blob
  
• Secret
  
• Mixed
  
• Extended
  

Uncommon:

• Gang
  
• Disaster
  
• Revolution
  
• Spy
  

Individual Antags:

• Wraith
  
• Predator
  

These are the gamemodes/antags you're like to run into on Goonstation. The questions are simple:

1) If you like one of these modes, what aspect of that mode makes it fun for you?
2) What is the essence of that particular mode; the thing that defines the mode in your mind?


I'm not asking for all of them; just pick your favorites. I'm only really concerned with what makes a mode for you, and you alone; no other opinions matter. I'm not even asking for both questions to be answered; just whatever you feel like.

Spoiler!

This is driven by resurgence of revolutionist. I noticed different people had different definitions of what makes rev, rev. The thing that, if taken from rev, causes rev to become something else. There were also disparities in what made rev fun for people.
