Some of my first games were IF. Well, this is pre-Internet, social media, and we have a very limited color palette -- yes, I am dating myself. The last couple of years I did a 360 degree and I am back into game design, as a faculty. I am in the process of getting my arms around the categorization of games based on which dimension they should belong to. Most of the games were easily categorized. One of the exceptions is IF. Which dimension do you believe IF should belong to? I thought possibly 0D or 5D. Your feedback would greatly be appreciated.

Please note that a game dimension is based on a mathematical (coordinate) system's perspective. However, it is not constraint to counting number (1D, 2D, 3D, 4D, etc.) It can be 0D, 2.5D (Isometrics) and possibly applicable to the real number system.

Example of a 1D: 1D-bobble (http://archive.globalgamejam.org/2012/1d-bobble)

Examples of 2d: typical solitaire and platformers

Example of 2.5D/isometric: Qbert (http://www.freeqbert.org/)

Example of a 3D: Minecraft

Example of a 4D: Miegakure (http://miegakure.com/)

Thank you for your feedback ~Thiep Pham.
