Old-school gaming can be a bit brutal.  For instance, if you can’t handle that character fatalities can and do happen or feel like mapping isn’t necessary to success then there may be a disconnect in expectations.

Also, old-school gaming often has no interest in your character backstory or concept other than how you play your character (“levels 1-3 are your character backstory”).  Story is what you make, not something preordained for your character.  There’s a different style of play going on here.
