Question: Is Saint* Dragon worthwhile?
*ST or St.
Answer: Yes, Virginia, there is a reason to own it...
(1) If you are an old-skool shoot-em-up fan, then you should check it out because it wasn't widely ported to consoles. It is certainly worth some of your time, since there are many, many horizontal shooters that are less exciting/more generic than Saint Dragon.
(2) You are a dragon with an undulating body!
(3) If you aren't an old-skool shoot-em-up fan, you probably won't find ST Dragon particularly endearing.
(4) I like the quirky aspects of SaintDragon. The game has an awkward charm. Awkward.
(5) It makes an excellent keychain. See below:
