The Crashed Frigate is really underrated. What area do you think is underappreciated in the Prime series?
Recently I've been playing through the Prime series, I've gotten through 1-3 and I'm super impressed by the visuals throughout them. I love the smaller designs of the rooms in 1 and 2, which really keeps the spirit of the older games intact and allows for a lot of attention to detail. Though 1 lags a bit through the end for me, the Phazon mines personally being a low point, the Chozo Ruins, Tallon Overworld, and Phendrana Drifts all do an incredible job with each setting and are incredibly fun to explore.
The visual fidelity of Prime 2 is honestly a genuine step up I felt, even if the areas maybe aren't as memorable as Prime 1 for me, I really love the fortress with all its intricacy and Torvus which has such a great theme, and of course you can't forget the rain, which feels like it goes so hand in hand with Metroid.
Prime 3, while honestly from a gameplay side was quite difficult for me to get through... Actually has some pretty great areas with lore I felt was pretty interesting. Elysium no doubt was the high point for me, amazing music, I loved the backstory, and the whole atmosphere was so good. Second pick would probably be the Pirate Homeworld for me, with all its orange and red just feeling really heavy and what you'd expect from such a hostile place.
I haven't gotten to Prime 4 yet but I hope too soon, I know reactions are mixed but as long as there's some cool areas I will definitely enjoy it I think.
