Accusing one SF property of "Ripping off" another is 100% unproductive for the genre. The reincorporation and combination of existing ideas is how new ideas are created.

Mass Effect is literally just Babylon 5 and Battlestar slapped together and painted over, and it& #39;s amazing.

Short of literally setting things in other people& #39;s universes which I absolutely do not approve of, I& #39;m totally in favour of taking heavy inspiration from old IPs to create new ones.

The genre desperately needs new IPs, but they don& #39;t all have to be hyper-original gamechangers.

Wing Commander is a great example of this. It takes a colossal amount of inspiration from Star Wars. But it doesn& #39;t matter.

WC is it& #39;s own world with compelling characters and emotive journeys, who cares if it has a similar vibe to some other thing?
