In a fantasy campaign (such as D&D) if the players find a magic item they generally have to find out what it is, how it works, whether it is cursed, etc.
In a post-apocalyptic (in my case futuristic) campaign, how would the players find out what the strange gun, for example, they found is? I don't want to simply say "You find a gun that gives you +2 to hit", but I'm not sure what other methods that the players can use would be best.
Obviously, they could go to a specialist in whatever weapon they've found, or experiment with the item they've found, or use some form of analysis that I could introduce (special computer, use a certain skill).
I feel I may be missing something, but that may simply be because I am used to players finding items and using 'Legend Lore', 'Identify', and so on.
What have you used in the past? And how well did it work? Am I missing a really obvious solution?
P.S. the system I am looking at in particular is Stars Without Number, but I believe this question to be at least partially system-generic.
