| Identifying which revision of my book you have |
| 6 | Sep 23, 2009 to Nov 10, 2009 | 2/3 of the way down page 14, you should see "(00000000)" for a color reference instead of "(FF000000)", found directly above Knuckles's speech. The book is 258 pages. |
| 7 | Nov 10, 2009 to Jan 22, 2010 | 1/4 of the way down page 21, Knuckles's first and longest bit of speech has "Was that was I was sensing?" instead of "Was that what I was sensing?" The book is 258 pages. |
| 8 | Jan 22, 2010 to Feb 16, 2010 | The back cover has the ISBN on it and the copyright page does not list the revision number. The book is now 273 pages instead of 258 |
| 9 | Feb 16, 2010 to Jul 25, 2010 | The back cover has the ISBN and the copyright page lists the revision number as the last line. |
| 10 | Jul 25, 2010 to Feb 15, 2011 | The copyright page states "tenth revision" and stat windows use "action rate" (the offical name) instead of "actions per second". |
| 11 | Feb 15, 2011 to Nov 19, 2011 | The copyright page states "eleventh revision" and the casting of barrier 89 is added on page 87 (due to an oversight). |
| 12 | Nov 19, 2011 to present | The copyright page states "twelfth revision" and "max defense ability" is replaced with "invincibility" in scene 14 (I couldn't think of the term at the time). |
