While not offering much for veterans, if you haven't experienced the Prime games before, this compilation is an outright steal and you owe it to yourself to play it.
When the Gamecube launched, people were completely skeptical that Retro Studios, a largely unknown studio in Texas, was taking the reins of the Metroid franchise, a beloved series that missed the entire N64 generation. The doubt grew when they heard this revival was going to be taken into the first-person perspective. But once the game launched, Metroid Prime was hailed by both fans and critics as not only an amazing entry into the franchise (if not the best) but also as one of the best games ever made. Not only did it feature a very unique control scheme, it also invented an entire genre: the first-person adventure. Despite the perspective, the game maintained Metroid's classic gameplay, tying exploration and action together almost seamlessly.
