2nd paragraph and image |
On page 67, talking about the Social engagement loop, the sentence above the image doesn't align with what is shown in the image. The text says Motivating emotion, then Player Re-engagement. The image however festure Motivation emotion then Social call to action. So, which is the correct flow?
I bought my book from Amazon using the Kindle app on my iPad.

Figure 4-7 |
Figure 4-7 shows the social engagement loop as
Motivating Emotion ➔ Social Call to Action ➔ Player Re-Engagement ➔ Visible Progress / Reward
However, in the text and in all examples (e.g. on pp. 68 and 69), the loop is actually (and more logically) described as
Motivating Emotion ➔ Player Re-Engagement ➔ Social Call to Action ➔ Visible Progress / Reward

Figure 4-7 |
The text says:
"In a social engagement loop, a MOTIVATING EMOTION leads to PLAYER RE-ENGAGEMENT, which leads to a SOCIAL CALL TO ACTION (...). Figure 4-7 illustrates this concept."
But the Figure 4-7 shows a different flow. It shows:
MOTIVATING EMOTION -> SOCIAL CALL TO ACTION -> PLAYER RE-ENGAGEMENT-> (...)
The rest of the book sticks to the text representation so only the figure is incorrect. Funny enough, this figure is widely copied and adapted across the internet. Any source I found that was talking about this topic had the idea represented wrong because of that logical error on one picture. Haven't found any information on reported corrections.
Have a good day!

4th paragraph |
There are 2 code snippets:
class User
belongs_to : level
...
class Level < ActiveRecord::Base
has_many :users
...
And in the next sentence:
This describes the "User has many Levels" relationship...
I think it must be:
This describes the "Level has many Users" relationship...
Because every user has only one current level (level_id), but one specific level may be achived by many users. As also said by the code snippets.
