What does create video game include?

A long time ago, maybe around 20 years, I did custom levels for RTS games and shooters. Earth 2150, Source engine, Serious Sam, Quake engine, etc. At some point I also did some 3D modeling. Then I participated in a Source mod community project, as part of a team; a Stargate themed mod.

More "recently", I created (an) Ultimate Tic-Tac-Toe (cross-dimension, cross-playing-fields tic tac toe), personal game jam project Energy Consumer (mainly a programming exercise given the limited time), game jam project with a friend Frogventure.

All other dabbling, interest, and ideas have not concluded in any significant development or products, partly due to lack of motivation and connection to people or people's interest.
