: How are game replay files so small?


To give a concrete example, I play this game called world of tanks blitz. They have a replay system where the replay file itself is <1MB and can be imported into the game client to view the entire game footage.

So my question is how do these replay files store the entire state of a complex game like this with many factors in <1mb?

In: Technology

Can you view it without internet connection? My first thought is that it contains information to reach their database rather than storing a video

PS: world of tanks is awesome. Playing it right now
