Why did the movie Avatar contain so many ideas from video games like

[Flingershock (Suspended)]

Mechwarrior, Halo, and Turok? Was the producer a major buff of all those games?

There were mechwarriors in the movie, those Pelicans from Halo 3, and all the dinosaurs from Turok.

You... do realize that those games stole most of those concepts first, don't you? (In particular, Halo 3 ripped off the pelicans from on of James Cameron's other popular films, Aliens... you're saying he's ripping off an idea someone ripped off of him? XD)

Pelicans were taken from the movie Aliens (Also Directed by James Cameron)
Vertical Tanks/Mech have been out far before Mech Warrior (See Gundam)
And Turok didn't invent Dinosaurs
