It is indeed - It’s causing a huge stir in game dev circles at the moment.
Loads of shiny bells and whistles obviously but the big thing for game dev is Unreal are trying to demonstrate an asset creation system where assets can be auto generated to photo-realistic fidelity (all the buildings are computer generated rather than hand made) and for prop objects, we’ll never had to make them again because they aren’t going to look any better down the line.
It’s something developers have been hoping for, for a long time. Generating a city takes a phenomenal amount of effort and it’s like reinventing the wheel every time. A lot of art work is outsourced to studios in India at the moment but I can see the next revolution being that we don’t need to create anything any more as we’ve already got what we need. It’ll be fascinating if that gets pulled off.
