Is there a good paper based solution to keep track of NPC stats so they are avaliable when you need them in-game but don't take hours to keep up to date?
I have a bunch of NPC notes and lists of names etc., but during a game I generally wing it as far as actual stats and skills for the NPCs. I don't currently make full profiles with all the stats and skills for each NPC as this would take a long time - so these stats simply don't exist.
I tried having little mini-sheets with the names, basic stats, and motivation guides on them - but in practice, I could never find the one I wanted at the right time and I often found that even if I did find it, it didn't have the information I needed on it anyway.
I don't play a rules heavy system, so it doesn't matter that I don't have all the stats to hand - however I think that making them up on the fly all the time may lead to too many inconsistencies and lazy fudging. Also having NPCs with unexpected talents or weakensses would add interest, but would need to be kept track of somehow.
Is there an organisation system that suits this kind of thing?
