I feel like I have a very idiosyncratic approach to spoilers in video games, and it's very related to how I grew up playing them I think.
Basically, I can divide things into three categories.
Things I don't want to be spoiled for:
- story
- endings
Things I don't seek out but don't mind finding out if I run across them:
- mechanics I haven't yet discovered/enabled/figured out
- the existence of particular puzzles or game events that aren't tied to specific plot points
- characters (name, appearance, disposition, etc) again that aren't tied to specific plot points
- the way areas look or function
Things I absolutely will seek out if I want to:
- solutions to problems in the game that I've spent time figuring out but am getting tired or frustrated by
- mechanics I've discovered or enabled but can't figure out
- deeper lore about plot I have experienced
- where collectible-quest stuff is after I get bored of looking on my own (think grubs in hollow knight, heart pieces towards the end of a Zelda game), especially if the alternative is I just won't bother, and double especially if the collectibles make a very hard game easier (like mask shards).
Basically this is the kind of stuff I grew up getting from Nintendo Power or kids at school. I just.. don't think of video games as a solo experience, even though I mostly enjoy single player games.
Which honestly kinda sucks these days because there's no real middle ground online. Half the internet thinks spoilers are evil and the other half thinks if you want to know one thing about a game you want to know *everything*.
