Props
One word that brings to mind LARP’s, or at the least a bunch of guys sitting in their parents basement with cloaks on, is prop. So lets fix that. Props are great tools that can help players feel a connection to their characters and the world around them at large.
For instance, in one campaign I ran, one character got a note that was incriminating for an NPC. The player hated the fact that the rest of the group gave up the note. Now I had typed the note and dyed the paper with coffee and crumpled it up. It looked cool and it was cheap and fast I think I spent 10 minutes working on it. I remember the players crowding around the page when I handed it to them. The fact that they traded something that was not much, but the value of this little clue became much larger. I then made that part of the bigger plot. So props can change the direction of a campaign. So keep that in mind.
Well what can you do as props? Maps that you hand draw or do as printouts. Notes, Journal pages, ID’s, Passcards. The list is endless, you just need to think about the things the players will interact with in a physical manner. If they mess with something then think of how you might make a prop out of it. For those really ambitious these types of things can be the memories that people have from the game. Some things to do get a ton of cool looking fonts from hand writing to graffiti to wingbats. Those can help to add little bits if you have the time learn to use a graphics program as well. They are invaluable skills and if you post them others can get some use out of everything you create as well. Get a laminater and use it for badges. Get a big collection of head shots of people. Those are useful even if you just need to grab one for an NPC.
So now you see there is something about props that is cool and makes the game better. Plus you don’t have to be a guy sitting is his parents basement to do it. Though those guys do have the time to make great props.
