It's been started as an answer to this question:

I *think* that distro/.live-kiosk is where use/live/runapp
should be, not the downstream distro/.live-games, since
the whole mini-feature is really about kiosks.

OTOH blender is somewhat akin to games in terms of being
a purely multimedia app with 3D acceleration required
for proper interactive mode, and that's what .live-games
strives to provide.
