Build Mode

Build Mode is a removed feature on Roblox in which players could use stamper tools to build a game. Instead of making the game in Roblox Studio then testing it when it was done, players were able to build the game as they were playing the game. The tools used were exactly the same tools used in Welcome to ROBLOX Building, a game made by. Players used this mode as a fast and easy way to make games without scripts and free models.

Criticism
During its lifespan, Build Mode was criticized for not allowing much freedom for editing a game and for causing a rush of poorly built games. Due to the said criticisms, most people steered away from the Build Mode.

Removal
In late December 2016, Build Mode was quietly removed. Unlike most removed features, the removal was unannounced on the Roblox blog and Roblox's social media accounts.
