Yeah Silpheed is a great example of designing a game around the strengths of its target hardware. Because they were able to focus the art design around what could be streamed at high quality off a 1x CD drive, the FMV works a lot better than it did in games like Night Trap and Wirehead that tried to shoehorn live action video into a console that wasn't capable of displaying it at a decent quality. The actual gameplay is similar to an early 1980s arcade game like Galaga, but I agree with you that the presentation makes it worth playing at least a few levels of Silpheed even now.
