For Icar version 4, I am putting together a series of cheat-sheet handouts that the players/GM get to use. The GM one is quite easy: group the rules into a series of sheets so that they might stick them to a screen. Also, the GM will have tables with weapons, what sort of damages they do compared to armour. That makes balancing the bad guys easier. The GM can then print the ones that are most useful for that session. For example, the space combat rules aren't that useful until you have some - which in the example Scavenger Setting might be a way off!
The more difficult task is the player one. Ideally, it should be 1 side of paper with all the rules and info they need to get started. What gets included on there?
Some simple taking action rules are easy enough but what about setting information? When getting to know important NPCs, it can be useful to have the names and faces there.
What do you think?
