Which features of the Tetris Guideline would you most like to see changed and why? "The Tetris Guideline is the current specification that The Tetris Company enforces for making all new (2001 and later) Tetris game products alike in form." If a company wishes to obtain a license to produce a Tetris product, their product must conform to the official Tetris Guideline. More information regarding what the Guideline is can be found on our wiki: http://www.tetrisconcept.com/wiki/index.php/Tetris_Guideline If you have suggestions on how to improve future updates to the Tetris franchise, now is your chance to have a say. Are there any present features that you think should be changed or removed? Are there any features from older games that you would like to see reinstated? Do you have any suggestions for completely new features which could be added? Some things that you might like to consider: the Random Generator number of NEXT previews the HOLD piece T-Spin rewards back 2 back rewards other scoring mechanics multiplayer garbage distribution multiplayer garbage hole alignment the basic rotation system the wallkick/floorkick system move reset lock delay ("infinity") level of difficulty of single player modes "ghost" piece tetromino color scheme Sideways auto-repeat (DAS) speed and delay Soft Drop/Hard Drop locking behavior top-out conditions piece spawn location There are TTC employees who are willing to listen, so if you present your argument in a logical and objective (unbiased) manner, giving detailed reasoning to support your ideas, you will make it easier for them to present our case and potentially get things approved. It might be a good idea to focus on one or two specific features, and describe how they should be changed in as much detail and clarity as possible, rather than speaking in vague and general terms about the entire guideline.
