what needs to be changed in the Tetris guideline

[SimMarine]

For modes like 40 lines, it would really be nice if you could not start with the S/Z/O pieces.

I'll reiterate what I said on TC.

If the following were commonplace in authentic Tetris games, there might not have been a Lockjaw:

• Full description of scoring system in the manual. If it looks too complex when written down, it probably is too complex.
• Option for fast DAS.
• Encourage developers to add replay support.
• Other randomizers, so that "opening theory" isn't emphasized as much. Compare Chess960 to standard Chess.
• An endless mode that starts decreasing lock delay after 20G, in addition to the existing 200-line and 25- or 40-line modes seen in games like Tetris DS.
• Allow users to script the tetrion to develop training exercises.
• No region lockout. If possible, give everyone a chance on the same products no matter the country.

Let's try this for a rough bash at what garbage should be:

0/1/2/4 (there is an argument for a tetris only doing 3 lines, but 4 is generally accepted these days).
Twists (defined as the piece locking in a position where it cannot move left right or up) send an additional line.
If the previous 2 pieces also cleared lines, then send one additional line.

In summary: No back to back. No escalating combo damage. T-spins can now be done by any piece, but do half damage.

I don't think much will be changed no matter how much we complain. I think there is always going to be a "normal" mode that is the marathon/survival mode now, but we can hope for a "master" mode (probably would be called something different to avoide being accused of copying TGM).

If you add a time element into each level and you lose or gain points depending on how fast you go would balance a lot of the game out. Tetrises are a lot faster than t-spins and the time bonus could make up for the point difference.
