What Game Walkthrough Should I Do?

[IronGames]

Hi! My channel is about opening Pokemon card packs, but there are usually 1 and a half weeks between videos, so I need something to fill the slot. I decided on a game walkthrough.

Rules:
Must be Nintendo
DS or older
Try to keep it main, stuff like Mario games, Zelda games, Pokemon games, ect.
Thanks!

Would you like to do one of the Metroid games? it's Nintendo only.
