A Pre-Flight Checklist – I don’t leave home without a one-page sheet which summarises everything I want to convey to the players from the moment they sit down at the table. I've previously described this in detail here. By setting this down in dot points I make sure I don’t forget anything important, or have to slow the pace of the game later to cover off something I’ve forgotten to mention from the beginning. I find the list helps me structure what would otherwise be a bit of a rambling monologue.
Timekeeping – a watch or clock is essential. It can be remarkably hard to keep a track of time when facilitating a game, and it is fairly crucial that you keep your game to time, and aren’t forced to rush through the final scenes. Timing is not an exact science, and checking your watch will likely mean the players check theirs and start thinking about their next game, so I usually try and be discreet about it. I’ve noticed (as a player) that often somewhere between a quarter and a third of the total time allocation is spent on initial introductions and explanations. In a game where establishing the characters is important (Fiasco, Apoclypse World, EPOCH) this is fine, but in more traditional games with pre-generated characters this often means that the final scenes suffer.
Maps – Maps serve two important functions. First they obviously convey relative information about places, which can be useful to emphasise information already provided or illustrate simply something which would be complex to describe. Second, they implicitly tell the players that their characters are on the right track or operating within the anticipated scope of the scenario. I often find that maps can be a useful synopsis of key information both at player and character level. The key is to have them be as simple as possible, to avoid having the map become a distraction for the players.
Pictures or Art – as with a map, a picture can convey a lot in a much simpler and more artful way than can easily be described aloud. I particularly use pictures when there are multiple NPC’s in the scenario (and hold up a picture of which NPC is talking to be absolutely clear for the players) or when there are monsters which might prove challenging to describe (stay tuned for my forthcoming post on Cthulhu Mythos monsters as an example). Art can also be useful to convey mood and setting information, something I note that the grand experiment has made particular use of when running his scenarios. When I picked up his scenario to run at short notice, the pictures included instantly and powerfully communicated a lot of information about the style, setting and intent of the scenario.
Name Tags – regardless of whether the players know each other before your game, they will soon ideally be referring to their characters by name. To enhance and encourage this, you ideally want to provide name tags so that players can read, at a glance, character names. Whether these are labels, folded pieces of card or laminated badges, a small effort before the game can make it that much easier to embrace characterisation.
GM Screen or Rules Reference – only rarely do I use a GM screen raised at the table as I think it dampens down the collegiality of the game (and I never roll dice behind a screen), but I often leave it lying flat and use the table for rules quick reference, but even having post-it notes in a rulebook would suffice. The secret is to flag any rules which are complex and likely to crop up during the scenario, so the exact text is at your fingertips. Ideally you will make the core rules accessible to the players as well, either by putting them on character sheets in short form, or creating tabletop quick reference guides.
The Basics – There are a couple of more basic things you should also cover off for an optimal experience; if your game uses dice, bring enough dice for everyone, you don’t want the game being slowed at a crucial moment while people go searching for their dice, or ask to borrow some. Bring enough pens or pencils for all the players - again, waiting to get a pencil to track damage or write a note can slow the flow of a game. Consider laminating handouts or other materials to try and avoid the table becoming a sea of paper and minimise the damage of an inevitable drink spill incident. Have a copy of the ‘con timetable nearby so that you know when your round begins and ends as well as small scraps of paper for notes (both for yourself and the players). And obviously make sure you have a copy of the scenario, relevant rules and character sheets ready to go.
