Speedrun is basically completing a game as fast as you can in a determined category (Or complete a determined category as fast as you can). The most common categories are either any% (Simply completing a game as fast as you can) or 100% (Completing everything in the game or, in some cases, completing everything that is considered 100% in the game).
Tool-Assisted Speedrun (TAS) is pretty much the same as Speedrun, but it is done in a different way. While in a normal speedrun the player does everything as fast as he can, the TAS slows down the game to execute the perfect movements while using of tools (Such as save-states) to go back in case something goes wrong or for luck manipulation.
In speedrun, timing works at the very start of the game (Usually after the start button is pressed) and finishes either at the last hit on the final boss or when the player loses control over the game. The TAS timing starts from the beginning and ends at the last input pressed (So such things as menus at the start of the game counts).
So feel free to discuss about any Speedruns or TASes of interest, any games that you wish to discuss fast strategies and tricks, games that you think it might be cool to watch a speedrun/TAS, show the Speedruns or TAS runs you worked on. Anyways, feel free to talk about anything speedrun or TAS related in this thread.
