RTB's Heyday is a time in Blockland's history around 2005~2007 where RTB was at it's pinnacle. There were thousands of players, and many clans such as O2D, PYRO, RM, and various others. Normally, anyone who never played during this time period weren't considered Senior Members. The Heyday soon ended after Retail was released in late February, 2007.
Afterwards, half of the population quickly moved onto retail, while many of those who stuck with 0002 would protest Retail and a large portion of that population would leave off by the middle of 2008. Those who still continued to play RTB would interact with a few hundred other players for a time.
