BC Beta Features were responsible for Builders Club members testing features such as Body Meshes, Personal Servers, Mega Places, Group Building were part of BC Beta features, and were discontinued as each feature became accessible to all users. Some were discontinued and replaced with new all-user features, and others are now available for any player to use. Most BC Beta Features were removed in 2011, the last being the Personal Server in 2016.
Main article: MEGA Place MEGA places were games whose servers could hold up to 50 players with a reduced amount of lag than normal due to increased capabilities of the computation power with additional players. MEGA places used more of ROBLOX's server resources and were only allowed to be created by Builders Club members. MEGA places were officially released in August 2011 after several periods of testing with 100 players on ROBLOX's game testing sites. MEGA places were removed at some time in 2014, most likely July 28th (that date was once stated on this article talking about how that was the day NBC users could start using MEGA places, but it was not proved with a source, and NBC members were actually never able to use MEGA places but could make places that allowed up to 50 players after the removal of MEGA places). After this happened, all users were able to make places that could have up to 50 players.
Personal servers, which were also a feature limited to Builders Club members, were automatically made a MEGA server. After an unknown time, they removed the picture symbolizing that it was a MEGA place. They did create, and keep the picture that shows that a game is a Personal Server. Until recently, it was going to be removed.
Groups often made their places 'Mega' as they could hold much more members of the group than a standard server.
Main article: Personal Servers
Personal servers were only available for BC members and could hold any amount of players. Players could be promoted or demoted by in-game administrators, as well as participate in collaborative building. Unlike game places, changes made to the place were preserved, as the server would stay online 24/7 and never close. Personal servers were also used for group games since they could follow group rankings.
Personal servers were discontinued in June 2016 with the release of Team Create, and all personal servers have been reverted to game places. Team Create has similar features to personal servers, except that place owners can turn it on off, as well as only invited users may edit the place.
VIP servers are similar to personal servers, but they are game places and they have to be purchased by a user.

Main article: Group Building
Group Building was a BC Beta Feature that allowed users to build together in a group. It was removed in 2011, and it is now part of Team Create, in which players can edit and build places together.
