I'm currently playing it for the first time. 10$ was a steal. I don't know if I will play all three of them but I at least needed to play the first. So far I am impressed, very impressed. The world design is fantastic and the sound is beautiful and additive, I am also impressed with the open endedness of the gameplay, and how having to read the notes makes it seem like you are truly alone and it feels like a true adventure instead of todays "Go here and do this then come back" approach to most games. However one thing I am dissapointed with is the constant revival of enemies that take sometimes minutes to kill and yield no reward, it eventually becomes extraordinarily tedious. But overall I love the game and am very happy Nintendo put it up for sale. Lets hope they start releasing gamecube games soon!!
Oh yeah, first time through trying to find your way you do end up doing a lot of back and forth looking for the way to progress, which would end up reviving a lot of enemies.
That doesnt last very long.
A few tips to help you alleviate some of that tedium, which overtime will add up to a much more enjoyable experience.
Unless there are locks on the doors, you dont have to defeat the enemies to advance, simply ignore them and head to your next door. Typically, there will only be a destroy all enemies encounter the first time you enter a certain area, although, some notorious do force you to deal with the locked doors every time.
Dont be afraid to use missiles, you will get plenty back, and use charge shots over normal shots for anything that doesnt die with a couple shots. A charge shot is worth more than 10 normal shots, and a missile is worth almost as much as a charge shot, and they both have splash damage,so they can take out multiple foes. Loosing a charged shot followed by a missile is typically enough to send any cannon fodder pirate on its merry way to hell, without you ever stopping your path to the next door.
You will soon start finding weapon power ups. And more weapons powerups. And more weapons powerups. I will not spoil anything for you, but there will soon probably come a time when you could almost start to feel bad with the constant reign of death and status effects spewing out of your arm upon all the hapless respawning baddies that are irritating you now. Metroid in general, but this game in particular, have one of the highest and swiftest rises to power in videogames, you become Techno-God. To emphasise your god like status over the pathetic mortals who are unfortunate enough to exist in the same time space as you, there are also super weapons in the form of beam missile combos. There are 4 total, you only get 1 automatically, the others are hidden, and missable. But oh so damn satisfying and room clearing.
