MGSV's online system

Why does online suck?

• Whenever you connect online, it redistributes your resources between offline and online.
  • Generally, a small amount will remain offline and all the rest will go online.
• If you spend stuff for online stuff, it comes out of your online resources.
• If you spend stuff for regular (offline) stuff, it typically comes out of your offline resources.
  • This can leave you deeply in the negative if you're ever offline.
• Being negative is very bad and can lead to staff leaving.
