I'll start this comment with a Spanish saying, "Aunque la mona se vista de seda, mona se queda," which is to say, "Even if a monkey dresses in silk, it's still a monkey." This saying will serve its role at the end of my comment.
Now, according to what Jack T says at the end of the game, the message is one of environmentalism. But, I don't see it that way.
When I watch this longplay, I can't help noticing a major difference between the dinosaurs and the humans, particularly their behaviors. When a human is defeated, that's the end of his life. But, when a dinosaur is defeated, it gets up and walks away. To me, that suggests that the dinosaurs have a knowledge the humans lack, the knowledge of when to walk away from a fight.
Fessenden, the final boss in this game, clearly thinks the greatest strength of the dinosaur is in their physical attributes. So, he turns himself, and others, into dinosaurs. But, it seems to me that he misses out on the true strength of the dinosaurs, the knowledge I mentioned. It seems to me that if Fessenden had studied the dinosaurs and learned from them when to stop fighting, he would have had the best of the two worlds. But, instead, he missed out, and proved to be nothing more than a monkey dressed in silk.
From what I could tell, the environmentalist message of this game was just secondary. The real message was something on the order of "Learn your limits."
Also, don't you just love how, in the victory scene, when the points are being counted, Jack's unintelligent look? "Mouth open, mouth close."
I was hopeless at fighting games, but I remember this in a cyprus or spanish arcade as a kid and I loved it. I got to either the small guy with the machine gun, or the lizard thing about a level later before I always died or ran out of cash lol. Loved the multiple health bars too
One of the most funny and enjoiable games that was found on coin-op. The last time i saw it, i were in the third year of secondary school, so... 1995. Damn, 18 year passed since the last time i saw this game in Arcade room!!! :-)
