I dunno. I enjoyed Save the Earth for about a week, then I just got tired of it. I think for me it was just too easy. It's more of a personal anti-recommendation than anything. I play it once in a while, only because there are a ton of monsters in it, but beyond that I think DAMM and War of the Monsters were the best kaiju games I've played.
Agreed. I finished everything in the game in about a weeks time.
