Metroid 1 is an unplayable wreck.
Just play Zero Mission, it turns the worst game in the franchise into the second best. (behind Super)
The only other game that I might tell you to skip is Hunters. I really loved its multiplayer, but that's gone now so there's no reason to play it. Campaign is pretty terrible, although seeing new bounty hunters is cool (one thing I really liked about Corruption). I really hope we get a new Metroid Prime Hunters, except on an actual console to really flesh out its multiplayer, and also give it an at least decent campaign.
