That was a long reading material I have not read in over a decade. I knew I recognized that chart, and readout. I think I stumbled upon that long ago and read it just the same. Was pretty interesting for a broad analysis of the games at the time. I have played a few of those type of games in the past, that the term refers to.
Saying that, I am primarily explorer, minus the extreme portion; with a mix of social and achiever. Although I go about the achiever a little differently. I don't compete with others, as that is not my concern. The only competition I have in me is with myself, to improve on my own ground; setting my own goals. With the social aspect I am neutrally centered, as I tend to listen to others in their conversations, as well interjecting into them when the topic interests me. Between solo and multiplayer is where social lies, as I may be in the mood for either or both.
The way I see it though is like what someone else mentioned though that there is quite a bit missing. Creator being one of them. I am a Builder at heart, but not always wanting to build, it is just most times. Multiplayer that shifts a bit away from building and goes into social usually with a touch of the achiever. Exploring will always be the primary, as I explore the many materials out there to build with to spur my creativity in what I build or creative. So i guess the closest to creator would be explorer & achiever line, to do with interacting with the world by changing it to something else when or if needed; if not just adding to it, which is where the goal oriented bits would be.
Having an overactive imagination helps with my explorer needs, although I don't really experiment much; so a soften tone in that area while it being the strongest. Like to try out new things, but also like seeing what I can do with the old ones too, especially mixing the two. The only experiments I guess would qualify would be in design for buildings. I don't exploit glitchs, bugs, or the like, as I find that a little boring, and hence the reason for me saying not to the extreme end of that spectrum. One thing that is an explorer trait would be adaptability, which is something I tend to be mostly, when not building.
