Just beat the first Metroid (NES) game - for the first time in my life ever - sometime this past week.
Back when I was in grade school, seeing anything else other than Brinstar was absolutely amazing. I could never get through Norfair, and I never even saw Kraid or Ridley, and the only reason I ever got to use the Wave Beam was because I used the Justin Bailey code - knowing that Samus was a girl was another interesting thing, but if you really look at it, Samus's armor had a sort of female sculpture to it, rather than a masculine one; kind of has that dynamic that slims at the waist, and it looked tight-fitting, too.
Finding the first Ice Beam used to be tricky; you had the bomb open the floor of one of the connecting bridges that had yellow lava at the bottom of the screen - the yellow lava being only an illusion - and climbing back up was always a chore, even after you got the Ice Beam.
Kraid's and Ridley's boss battle patterns were pretty simplistic, but actually rather difficult to break through; both had ton of hit points. Kraid was harder, even if you're supposed to tackle him first. He shoots 3 needles out of his chest, and tosses 2 spines out of his back, thrown at an angle at you. His needle projectiles deflect your own shots, but you can freeze them in mid air, along with his spines, and go in close, and plug him with missiles, bombs, or your Ice Beam. Ridley was easier, the fireballs he blew at you, you could just safely somersault through those with the Screw Attack. Again, your choice of bombs, missiles, or Ice Beam, but I thought he went down easier than Kraid. I also think Kraid was harder, because he could more easily land you in the yellow lava on either side of the room.
Ridley took me about 2-3 tries to beat him, Kraid, probably double that.
Having all of your Energy Tanks full definitely helps.
Mother Brain wasn't too hard; you just have to plug her with missiles, and avoid getting hit by those ring-shaped biological whosie-whatsits that fly about.
Well, that "Yellow Lava," I don't know if that's what it's actually supposed to be, but that's what I'm going to call it until I find out what it's really supposed to be - marshes, maybe?
Ending was nothing special - short paragraph of text, and Samus changes out of her armor; you see her in a different outfit depending on how quickly you played through the whole game, and there's 7 different outfits you can see, with Samus being in a white bikini being the result for the fastest possible time.
Other than that, I'm just stoked I finally completed this game, and finally saw the parts of the game that I never did before.
