While mulling over the skill sets of Temperament Theory, I came up with the following aphorisms to summarise the four player types of "DGD 1.5" (i.e. Temperament Theory applied to games):
"Practice makes perfect"
"Give me the tools and let me at it."
"I can figure it out"
"We can find a way."
(The Diplomatic skill set remains the least clear in terms of games, since so much focus elsewhere has been on the Idealist's interpersonal skills which don't apply in single player games. Integrative thinking and the ability to deal with abstracts seem key, however.)
