I have to admit that FF7 is probably the only game I didn't play (for longer than first 2 hours or so at least) and yet I know such important "twists" due to the sheer amount of spoilers/"parodies" etc on the Internet.
Dragon quest seven, on the other hand, is a whole other beast, it takes literal hours before the first battle. Remake lets you move faster so it is a lot quicker to jump through the tens of hoops.
But yeah, big oof spoilers.
Sorry NASA-kun, but Aerith doesn't join the party with any equipment worth removing.
Man, I'm now remembering all those ridiculous theories to resurrect Aerith. Wonder if the remake will do something in that regard in the far future when its complete.
