I placed this question on one of the “stickies” above, perhaps that’s why no one’s replied… so I’ll post here as a new question.
Blender.org used to have some “runtime” demos of the games engine (one, was a “naughty nurse” where the mouse acted like a fly swatter - ouch!). The ideas although old were good starting points for simple projects, such as making a humorous blender-generated e-card.
…does anyone know where I can get these original runtimes from? They seem to have long disappeared.
