I know that if I really want to, I could easily knock out Metroid: Zero Mission in like 5-7hrs tbh? It's an annoyingly short game in hindsight and that's with me being constantly lost on what to do lmao
By that I mean "I have a very rough idea on what to do and where to go but I'm very easily lost"
Super Metroid? Say goodbye to a few days of my life as I get too frustrated to keep playing on that day, repeat, etc
