this will be all star wars in, what, 3 years? lol
Wait for Cameron to bring the thunder.
And yes, Valve games understand the relation of perspective on storytelling a lot better than most gaming companies. It's probably also the reason they haven't made Half-Life and Portal movies, despite that they were talking about it with JJ Abrams in 2014, and then we got Cloverfield 10 Lane, which was called 'the cellar', is made by a guy who directed a Portal short, and has literal Portal / H-L elements in it, as produced by Abrams in 2016.
But I'm sure that's just a coincidence. But, speculation is free! I personally think it's pretty obvious it was redeveloped though, since otherwise the project would be lost / sent to development hell. Gotta get something made if you wanna make money back. I didn't hate it for that or anything. It is mildly frustrating to know we can never have a H-L or Portal, or even Halo movie, though, since none of them can be directly converted. Halo might be doable, but the critical moment in its popularity has sadly passed.
