Why are Shmup games some the most expensive games on the App Store?
Just wondering why shmup games on the App Store are some of the more expensive games? I'm not complaining...just wondering if anyone here knows why. The Cave shmups Dodonpachi Ressurection HD is $13.99USD, Dariusburst SP is $10.99. Raystorm is $8.99. Dodonpachi Maximum is $11.99. Anyone?
