MMO video games have given a context for communities to live in virtual worlds—not just through the mechanics and world of the game itself, but through props and other elements of the virtuality that allow players to regenerate parts of their own lives. With the passing of the 4th of July holiday in the US, many MMOs introduced fireworks displays, items, etc.

The result of introducing props from external mainstream cultures, players bring their own cultural expectations into the game.

In Firefall numerous users have taken the fireworks props and regenerated their own displays in game; and now Firefall has added an official Forth of July-type celebration.
