Synth music style invented around 30 years ago on technology that didn’t exist a generation ago: "This sounds old-fashioned, the developers need to evolve."
Orchestral music played on instruments that have existed for thousands of years, in a style that’s existed for hundreds: “Finally, a modern sounding ost!” 
The most powerful type of viddygaem soundtrack emerged in the 1990s. Back when dev studios were first moving to fully digital CD quality audio, frequently it would end up that their One Guy was both a composer and like, a goofy guitar player. Frequently this Guy would just get a Yamaha keyboard or DAW thrown at him, and the end result was the composer absolutely shredding on guitar while a bunch of synth instrument tones played support.
Examples would be parts of Sonic Adventure’s music as well as the entire Castlevania Rondo of Blood soundtrack. Banger.
