Rocket Slime isn't for everyone. The quirky and sometimes innocent sense of humor is omnipresent. Why, even after a heated and bitter battle that ends in his tank being utterly destroyed, Rocket's rival will usually pay him a sincere compliment before scampering off in defeat.
Give this "kiddie" game a chance, though, and you may be shocked at how much fun you have. The only things you have to lose are 15-20 hours... and perhaps the heart to kill the gallant little gloops the next time you see them in an "adult" Dragon Quest.
