Metroid: Samus Returns
This is everything I've ever wanted in a brand new 2D Metroid game. I knew there was so much more potential in another 2D entry and Samus Returns has definitely realized that potential by incorporating modern video game conventions that refine exploration and vastly improve on already great gameplay mechanics. The 3D textures also look a lot better than I thought they would and add so much more depth to the environments while also allowing for more fluid animations and seamless cinematic cutscenes and interactions.
I also want to make mention of the 3D effect in this game because it is by far the best it has ever been utilized in a 3DS games. I remember when the 3DS was first announced, I assumed the effect was going to be more like the movies, when you see things popping out of the screen, but instead it just added depth. Here however, you have beautiful artwork that really pops, amazing backgrounds that usually have something going on, and even the 3D movie thing with ice shards actually flying towards the screen when you kill an enemy with the ice beam.
Overall, Metroid: Samus Returns is more than just a remake or a return to the classic Metroid formula. It may be limited by the premise and structure of the original Metroid II, but Samus Returns goes above and beyond to make this feel like a brand new experience. As I see it, there's no reason to ever go back to Metroid II ever again and the added lore really get me excited about the possibilities of a sequel to Fusion.
