People have made fun of the title... like in the listing for the RiffTrax it was described as a title abbreviation IN the title.
Seems to me it's quite simple...
There were supposed to be six films in the series. This was (obviously) the first.
Then there would've been (including this film):
Dragon Wars:
D-War
Dragon Wars:
R-War
Dragon Wars:
A-War
Dragon Wars:
G-War
Dragon Wars:
O-War
Dragon Wars:
N-War
With each film becoming more intense, and man, that 'N-War' would've
REALLY kicked ass!
The title was not referring to the name of the wingless snake/lizards, it was referring to the six lettered "D,R,A,G,O,N" wars.
Makes PERFECT sense now, eh?

Other theories?
