But seriously, this is a topic discussing Metroid games since it seems to be... taking the forum over... by a certain two people. You should know who you are.
So I have played Metroid for a long time. My first was Prime along with Fusion. I also had the original Metroid which came with Prime. I actually didn't get another Metroid game until I bought the Prime Trilogy, and then Super Metroid. I'm beginning to consider buying Metroid 2 on the 3DS VC and I would get Zero Mission but I can't for... REASONS...
Another time I got scared came in Fusion when I saw the Metroid shells on the ground throughout the sectors as the Omega Metroid evolved. I just knew that we would fight the end product of all those shells eventually.
Too bad the Space Pirates brutally murder countless creatures including their own with an immortal dragon (Even causing some to go extinct), preform terrible science experiments with a lethal material, stole aliens made by Chozo and used them as their own weapons, and ravage numerous planets to the point where they're unlivable.
Then the Federation breeds Metroids, 'kill Crocomire', and they're supposedly entirely evil.
I also replayed Metroid Prime and finished it today. Impact Crater was a lot easier to scale than I remembered. The Fission Metroids aren't that difficult to dodge, sure they're infinite but even if they do latch onto you they die in one Power Bomb. Either way...
IMPACT CRATER IMPACT CRATER IMPACT CRATER.
I'm replaying Prime 2 on Trilogy now, Veteran mode.
Metroid is one of the few game series I even try replaying. Back in the early 2000s I took way too much time playing around instead of completing the game. Out of the Metroids I have played...
Metroid (NES) - Never beat it for obvious reasons Super Metroid - Currently fighting Ridley Metroid Prime - I beat it on Trilogy, normal mode and I've almost beat the GameCube version I had for 13+ years myself (I watched my brother and dad beat it before but I didn't touch it quite as often). Metroid Fusion - Stuck on the SA-X battle right now... Metroid Prime 2 - I beat it several months ago, (Trilogy, normal) and I'm replaying it right now on Veteran. I'm almost at the Grapple Guardian who kicked my butt three times on my first playthrough so I'm kinda scared to touch it. This was the first Metroid game I beat, and I know some people still can't beat it. Metroid Prime 3 - This game I beat with the highest percentage yet. 84% on Normal, I think.
Technically I haven't beaten any Metroid - or any game - twice. Prime 2 will be the first to claim that title and it deserves that.
Yakuza, Nightmare, B.O.X., and Ridley were among the hardest of the Fusion bosses I'd say. Phantoon, Godlen Torizo, and Ridley are kinda tough in Super. I think the hardest part with Phantoon is how some of the attacks are seriously impossible to dodge.
