The last paragraph of the article was terrible, but the article makes me want to ask. How bad is the difficulty curve? Some games get progressively harder up to a point where I feel like I hit a wall and have no way to train myself over it and just lose interest. Typically Metroid has a near perfect difficulty curve where the end is hard, but it trains you how to get there every step of the way.

Also, Metroid isn't an RPG where you can grind your way to making it easier, but it does reward exploration and curiosity with making the game easier. Explore enough and you get extra health and missiles, making it easier to brute force your way through a challenge that otherwise might be too hard. It still has that, right?
