Dragon Ninja
Data East did do a good job of including plenty of references to their own properties into Bad Dudes though, in a way that wasn’t really done up until this point, creating their own sort of Data East culture.
Arcade
The Ninja Warriors
The Ninja Warriors definitely wears that it’s an arcade game that is meant to overwhelm you and take your money on its sleeve, even more than the arcade version of Spartan X did.
Gradius
An even more novel idea than introducing real enemy patterns is distinctive Gradius power-up system.
Makai Mura
Despite the unreasonable difficulty, I’ve always felt a lot of affection of this game from the first time I saw it in an arcade.
Double Dragon
Thankfully, Double Dragon does have an attack that’s practically guaranteed to get you through without too much trouble, as long as you get the timing down: The elbow smash.
