Oh no, it's Godzilla! Run!
When I turned this on there were a few little cut scenes and some text started scrolling through the bottom of my screen. It said "In the year 2XXX..." That's when I pressed start because I couldn't tell if they meant 2XXX as in "two thousand and whatever the hell you want", or as in "Ooops we just made a programming error, oh well stupid people will buy it anyway".
When you press start the screen goes black and it says "Earth". Then it takes you to a little chess board looking map where you control either Godzilla or Mothra. You have a limited amount of spaces that you can move, and then you unfortunately have to play a level. What is weird is that you are not even on Earth. You are on some planet, and you can see Earth in the backround. If you play as Godzilla you can punch, kid, jump, tail whip, or blow blue stuff out of your mouth. You will also deal with some of the worst clipping I have seen on the NES. Mountains and Godzilla will merge into one nasty piece of artistry. Now, if you choose Mothra there is no clipping to be found. There is plenty of slowdown though! If you get over about 4 enemies on screen at once your television suddenly becomes a Mothra slide show. The Mothra stages are a pretty basic side scrolling shooter where Mothra shoots little yellow balls out of his head. Taking everything into account, I would probably say the Mothra stages resemble something more like fun. Boss battles revolve around you standing still and pressing A as fast as you can.
The graphics are actually good when they aren't clipped or in slow motion. Mothra and Godzilla are probably some of the phsysically biggest playable characters on the NES. They are rather well detailed too. The enemies and level design meet the expectations you may have for the NES.
As far as sound goes, this game has a fairly quarky soundtrack that doesn't repeat itself too much, and won't annoy you nearly as bad as other titles.
The controls are decent. This is probably most likely due to the fact that it's hard to mess up games that require you to press your "A" button really fast.
Sure, the story doesn't make any sense, but this is Godzilla, not Legend of Zelda. My main gripe with this game is that it runs so poorly. You can find certain parts of this game and say "that looks pretty cool", but if a game like River City Ransom ran as badly as this game does know would know that game existed either. I would pay $4-$7 dollars for this game. It's play style is fairly unique, and it's probably worth checking out for a very low price. For a collector I would say $6 because there are not that many Godzilla games in existence. I still would recommend that as either a fan or a collector that you check around because there are a lot better games to own in that same price range. Godzilla Monster of Monsters is one of the last games I would purchase to complete a collection.
