EHOH is very fun but its playfield design is average and can arguably be somewhat clunky. It excels at theme integration, video assets and code, but personally I have a hard time viewing any game as an all time great unless it’s also an excellent and/or special shooter - like POTC. You could certainly argue that AFM and MM are also basic shooters that rely on theme integration but they have great flow and were “leaders” not “followers.” The EHOH castle is cool but is a distant follower to the MM castle. As far as playfield design and standing the test of time POTC is just in a different league IMO.
