Here are Teh Eras of Roblox!!! Researched and (partly) coined by me!

Era 0: Pre-release (ca. 2003-2006)

This was the time before Roblox's offical release on Sept 1, 2006

Era 1: Primiblox Era (ca. 2006-2012)

This was Roblox's first couple of years of existance. It's usally recoginzed as Roblox's "classic" period. It's during this time that the Awesomesauce era of Internet culture would have it's influnce in Roblox (+the 2nd Era)

Era 2: Stamper Era (ca. 2010-2016)

This was Roblox's first major increase in quality, following their introduce of Packages in mid 2010. Major changes include:

+ Roblox's 1st sponsored event, Zeke and Luther (March 2010) -

This Disney event would introduce Robloxians to the world of skateboards and the act of skateboarding, which would cause the birth of RoSkaters, a MAJOR piece of this era's culture!

+ Packages (known today as Bundles) (May 14, 2010) -

Gave players the ability to customaize their avatar's physical bodies. Iconic packages include Mr Roboto, CoolKidMcAwesome, and the 2.0 Robloxian, which was actually the 1st package to be released. They were actually disliked by a good portion of the community at release. Many believed that the 2.0 Robloxian didn't fit the blocky style Roblox was, and still is, known for. Though, Packages would become a favorite in the following years. I personally remember the 2.0 Robloxian being EVERYWHERE in dis Era.

+ Stamper Tools (Late 2010) -

The stamper tools series were a new fun way for players to get into Roblox building, even causals. They operated by having various tools for specific tasks: The Stamper would insert Roblox-published models and decals. It was used a lot in Personal Servers (2011-2016) and certain build games like "Sandbox" by NullSenseStudio and "Welcome To ROBLOX Building" by Roblox themselves. They would be removed in 2017 due to the deprecation of the IUnsertService, which the tool relied it. This service was removed to to its danger as it could insert any model thru exploits (NEEDZ CITATION. DIS IS JUST GUESS AND QUICK READING).
