You really don't have to grab spoiler free stuff. It won't make context outside of the game until you reach the part that it will be understandable, and by then most people have forgotten what was said. Seriously, please don't go the route of "everything is spoilers so I'll post nothing of interest instead" because you won't get many players that way.
Even FF7 and other games like it marketed by showing some of the more interesting content (like Sephiroth in flames and Diamond Weapon and characters you don't get til later on). Spoilers are fine as long as you're not straight out saying "Aeris dies".
