This is one of my alltime favorite games, and still the most prerelease hype I have ever had for one. Coming off how much I surprisingly loved prime 1, I remember the trailers and especially the gameinformer focus. Seeing all the official art of ing and dark aether was insane.
I know the long time beam ammo controversy, but I always loved it. Adding in thay extra factor combined with the intensity of dark aether. Prime 2 hard mode is probably the second hardest (official) metroid game second to fusion mode samus returns. I love all the areas even aside from the zelda-ish boss keys. The bosses are all great, with quadraxix being one of the best in the series. Just an amazing game and sequel to another amazing game. Even without ridley, but the start of dark samus.
