I played until 1:00 AM last night. At first, I leaned to my right to see the time on my router, which is obscurred by my monitor. All I could see was 0:56, so I figured it was only 11. Then I leaned further right, and didn't see a 1. Yeah, any game that makes me lose track of time is a winner.
If you enjoyed the oldschool Metroid more than Prime, or Prime felt more like a spinoff to you, this game is for you. I hope it sells well, because there is so much that Team Ninja could do with the series in this engine.
Starbu.. er, young Samus is definitely hot, and I wish they had kept her looking like that. I never did care for the Zero Mission art style, they look like two different people.
Some of the creature design here is downright creepy. Thanks to this game, I now have a fear of giant red-eyed turds coming out of the wall and trying to eat me. Reminds me of the ending of Eraserhead.
