Give Your Storyteller What They Want
Just as every player has those elements which make their eyes light up, so too does the Storyteller. Unfortunately for the Storyteller the game isn't being designed with their enjoyment paramount in their mind (or at least they shouldn't) nor are the players all sitting around thinking about how much they can make the Storyteller happy with every reaction and interaction. Now this is part of the joy and the burden of running the game. After all, it kills immersion for the players to focus on external concerns and also how arbitrary and dull would it be if the player characters all did what was expected or hoped for? Still it is nice to bear in mind what your Storyteller enjoys so that you don’t accidentally kill it dead. What might look like an irrelevant bit of frippery to you, easily avoided, might be the very thing that has motivated your Storyteller entire presentation. I’m not saying “Trust the obvious betrayer” or anything like that but perhaps try to enjoy the odd political encounter or detective work that your Storyteller throws in if that's what they're into. Maybe pay attention to that bit of historical research or world building they tell you about and find some way to make use of it in game even if it would normally bore you.
Have Faith in your Storyteller
Sometimes things will happen in the game that don’t seem to make any sense. Everything goes to hell. An enemy long thought dead resurfaces. It looks like your PC stands to lose everything. It might make you irritated or despondent with the way the game is going and you might want to take your Storyteller to task over it. Breathe a moment. Think about it. Think about your Storyteller. Understand that without conflict there is no story. Maybe the Storyteller is trying to build up dread and anticipation and things will work out in the end. Or maybe it'll all make sense once you get to the end of the road. At least hold back judgement for awhile to see if things really are as you fear. There’s no point getting angry over assumptions that a session or two worth of patience would’ve revealed to be unfounded.
Be Open with Them
If something isn’t working for you then let your Storyteller know. Maybe they’re big on political chit-chat whereas you’re keen on wild action. There may be room for compromise. Maybe you’d be happy to have all the social and political scenes if there’s at least one action scene per session – car chase, fistfight, bit or larceny, whatever. Maybe you’d be happy to deal with all of the action if there were an investigation to string it all together. Be sure to talk in terms of what you would like rather than laying out demands with lots of “You should’s” or, worse, telling them off by saying "I don't like THIS and THIS and THIS". You'll get more luck with positivity then negativity.
Let Them Know Your Triggers
Don’t force your Storyteller to guess at your personal triggers and no go zones. It may make perfect sense to you that you don’t want to see racism, domestic violence or sexual abuse in a roleplaying game but your Storyteller (or the other players) may see the game as a safe place to explore difficult issues. Some people love roleplaying romantic tension and sexuality. Others find it creepy and offputting. Be honest if there’s certain places you don’t want to visit even in fiction. Be honest with yourself, as well. There's nothing wrong with having boundaries if you're honest about them.
There’s little more draining than watching your players distract themselves with iPods, laptops, and reference books. If you’re a perpetual fiddler then a low-key activity like knitting or drawing could work to keep your hands busy and your mind on the game. If you constantly need mental stimulation than perhaps taking notes or otherwise thinking about the group’s next moves could help. While every group has their own Attention Expectations, if your Storyteller has to repeat themselves then you’re not attentive enough. Trust me, this is coming from someone with ADHD that is exarcebated by the kind of delays one gets in party-based roleplaying games (as opposed to solo games).
Develop your Protagonist
You’re going to have to settle yourself into the mind of this protagonist for long stretches of time so it’s a good idea to pick someone interesting and who has a nice range of skills that will allow you to do what you want to do. While it can be fun playing against your own type, if you’re a big fan of action then playing a bookish pacifist will likely drive you up the wall. There are many ways to play against type while still being able to get involved in the type of plots you like.
Engage with the Plot
Without conflict, there is no plot. Without plot, there is no game. While a certain amount of reticence is understandable – especially if the plot is quite dangerous – it can really grind the game to a halt if your protagonists refuse to actively meet the plot. Since artificial and contrived motivations often damage immersion and undo all the hard work you’ve done in character development, it’s often a good idea to come up with a few drives that could easily motivate your character to get involved. If your character is conflicted about whether to get involved or not, figure out what might give them that final push. Sometimes it might be simple as letting your Game Warden know: “My protagonist doesn’t want to get involved right now but she would if
Help the Mood
The Game Warden can set the mood but anybody can break it. If the game is a light comedy then comments that really reinforce the tragic tones of the game should be kept to a minimum. If it’s a horror game then keep your tension-breaking jokes in-character and ditch the movie references. If it’s a high action game then describe your larger than life actions.
Bring Your Own Gear
While some Game Wardens will have enough dice and pencils for everyone, it’s really not fair to expect them to do so. They already have enough preparations and purchases to cope with and this is really quite a small but nice thing to do to help take a load off their mind. If your Game Warden really is happy to take care of this for you then show your appreciation. They really are doing something nice for you on top of running the game.
Update Your Information
Keep your character sheet up-to-date, jot down your own experience points, and keep any vital notes to ensure that the game can run quickly and efficiently.
Let Your Game Warden Know It’s Working
Your Game Warden might not be able to tell if you’re really enjoying yourself – especially if the game is highly tense or has a lot of negative in character emotions. Sometimes you need to tell them or, better yet, show them with big smiles and much cheer after the session. It doesn’t hurt to tell them exactly what you liked about the session and why.
Optional: Keep Focused
Different groups have different expectations as to how much player focus and out of character conversation is appropriate. Different genres also have different needs in regards to this. Be sure that you’re aware as to what the group’s needs are and try to stick close to it. You can help keep the focus in the game by biting back the movie references and not encouraging other players to chit-chat. If focus isn’t a big deal, then you can safely ignore this, though it’s often a good idea to check that everyone is on the same page with this to ensure that your Game Warden (or another player) isn’t slowly tearing out their hair at your antics.
