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 problem.

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.
