GAME DESIGN THEORY & PRACTICE
SECOND EDITION

p.149
It has been reported that Pajitnov, in creating Tetris, originally considered
using pieces consisting of five squares combined into twelve unique pieces.
Indeed, the pentomino game from which Pajitnov drew his inspiration used twelve
five-square pieces. Pajitnov soon realized that this was too many different
pieces to have to manipulate in Tetris's high-pressure setting, where players
have a limited amount of time to find a perfect fit for a given piece.
Certainly a game using five-square pieces could have been challenging in its
own way, and perhaps a slower falling speed and larger play-field could have
compensated for the added complexity of the larger pieces. But would it have
been Tetris? No. Would it have been as fun and addictive as Tetris? Proably
not. At some point a complexity level begins to stifle the core nature of a
game and confuses players instead of challenging them. Using five insead of
four squares ruined the simplicity Pajitnov was striving for, and as a result
he reduced the number of squares a piece could have. Similarly, if he had used
only three squares, the game would have been too simple. It would appear Tetris
expertly follows the adage that everything should be as simple as possible but
no simpler.
根据报导 Pajitnov 在创造俄罗斯方块的时候，原本想使用的是五个方块所组成的十二个
互异的形状。的确，引发 Pajitnov 灵感的五连方块游戏，是使用十二片五方格的拼块。
Pajitnov 很快就发现，若限制玩家在一段时间内将特定拼块放置在最适当的地方，这样的
形状数量太多。当然，若使用五连方块会变得很有挑战性，并且较缓的掉落速度以及较宽
的盘面可以弥补形状太复杂的缺陷。但这样还会是俄罗斯方块吗？不。这会跟俄罗斯方块
一样有趣且吸引人吗？可能不会。复杂性太过只会扼杀游戏的精髓，并使玩家感到困扰，
而不会想挑战它。以五个方块取代四个，将破坏 Pajitnov 所追求的单纯性。同样的，假
若他只使用三个，游戏就会变得太简单了。(后略)
There are actually thirteen unique combinations of five squares possible, where
each square shares a side with another square. So it would appear that the
original pentomino game, with its twelve bolcks, did not use a complete set of
pieces. I have never tried pentomino, so I have no idea how much fun that
puzzle may be. Part of what makes Tetris so elegant is the completeness of its
pieces. Every possible permutation of four squares with squares sharing sides
is used in the game. Remove any one of the pieces from Tetris and the game's
balance would suffer. When playing, players will find themselves presented with
situations that cry out for certain pieces. Certain arrangements of the blocks
on the bottom of the screen leave holes that can only be perfecly filled by a
specific Tetris piece. Part of what leds Teris its balance is the fact that
Pajitnov was wise enough to include each piece possible, thus providing a piece
for every type of gap. The natural completness and symmetry of the pieces
available to players in Tetris is a crucial component of its balace.
帕索强调，五连方块真的只有十二个，不晓得作者为何要说十三个...
后面懒得翻了...
不晓得这部分是不是板主大大想要知道的部分？
