Final Fantasy Adventure
Game BoyNovember 1, 1991
As with many older games of this nature, most of the tutorial is in the extensive manual. But that's no fun.
Because Final Fantasy Adventure has one of the most ludicrous openings of any Final Fantasy-adjacent game by allowing you to name two characters (I went with "Boy" and "Girl") and then immediately throwing you into an arena and yelling "Now fight!" in your face.
And yes, you can lose this fight, die, and have to rename your characters. Incredible. Once you're successfully through, you'll be given some loose directions in poor English (R.I.P. Willy) and be forced to fight in the arena one more time before meeting Dark Lord (drop the "the") and kicking the game off in earnest.
No tutorials here. Now fight!
