Other than its application as a tool of cultural warfare and creating a market for Gallentean products ("Nerner, look at our pretty women and awesome lifestyles that we got and you ain't trolol"), after watching a bit of
Macross, I wondered if entertainment is more than just another boring RL Americanism adopted into GalFed PF.
As a sci-fi universe, we can expect any stageshows for theatre or music to use futuristic technology to augment the display for maximum "wow" factor, perhaps stuff like colour auras made by nanites (?!) or whatever. With holoreels, I have been exploring the idea of "VR movies" that replace the modern-day CGI, such as Anette lending her voice to a "bax" (whatever the hell they are). With hologames, I explored VR with
Wings of Valour.
Other than the technological side, the EVE world is far far less safe than the one we inhabit now. Sansha incursions, raids on remote planetside/deadspace colonies by pirates, collective threats, and so on. I was therefore thinking that entertainment isn't just a product of Gallentean aesthetic-driven culture and decadence, but also an important notion to rally around in times of strife and trouble. With a natural distrust of politicians and the government, the population may look to cultural and popular icons as a form of morale-boosting instead. In times of strife, singers will sing songs of mourning and so on.
I suppose it's easy to go "ogod elton john candle in the wind", but if one takes the above outside of a RL context and into a sci-fi one, it could potentially be more romantic and heroic than what we see IRL. Anyway, it's a way to apply something that is rather ordinary (as far as RL is concerned) within the EVE universe and applying it to the setting in an original and different way.
