From a GM's perspective...
When players insist that dice rolls are needed for everything and they insist on following the rulebooks to the letter instead of listening to their GM.
The GM is God with a capital G in the game. They are the essence and force of everything in the universe, just let them do their jobs and if they suck at it, then so bet it - get a new one.
Major pet peeve... When players lack enough creativity to think their way out a room with a unlocked door because they insist on using dice rolls to do it. (Wet paper bag metaphor)
- Stop trying to roll observations rolls or pick locks or whatever and just turn the bloody door knob you uncreative lack of imagination fools! You don't need dice rolls to resolve everything.
PS: Even if the door was locked, if it's made of thin wood, just kick the f@#ing thing in! Stop trying to make people roll dice for it! I'm pretty damn positive that your 290 lbs 6'6" tall Orc is capable of kicking in a tiny door with little to no effort... I won't make you roll dice for it.. don't make me roll them too.
On the same note.. Stupid GM's that ask you to make all those damn observation rolls and everything under the sun for obvious stuff like.. "It was sitting in the top drawer!" Are you serious GM? When I said.. "I search the drawers" You as a GM could not have figured out that I most likely would have.. you know.. opened the damn drawer? Why the hell do I need to roll for that?!
GM's and Players that insist on rolling dice for every piece of combat....
If the players highly trained hand to hand combat operative gets into a bar fight with some untrained drunkard... please for the love of all things.. don't make me roll dice for it.. not as a GM.. and not as a player..
Is it god-modding for a player to respond to that combat by saying, "GM, can I handle this person easily enough?" Of course it is.. but if the GM says it's alright.. then guess what.. it is alright... DICE ROLLS AREN'T NEEDED ALL THE TIME! The player should be allowed at this point to use one of his/her fancy kick ass hand to hand combat moves like it's a movie stunt scene if they want to.
Player should be allowed to say, "Hey, GM.. When the guy takes a swing at me I'll just shove them over into the wall, jump up and doing a flying round house kick to that persons face and knock him out."
GM should respond, "Hell yeah.. that'd be badass.. Alright.. no problem.. That person is down and out.... moving along then."
Stupid ass dice rolls annoy me, both as a player and as a GM.
Lets just get on the with story and/or adventure and feel free to have a little fun and let loose with your fancy abilities once in awhile just for the sake of fun.
Not everything has to be about rules, dice and what the books tell you. If something doesn't make sense in the moment(or in the books) then defer to the GM's judgement and just enjoy the role playing.
Training. A lot of the early games have this 'issue', because they were based off war games/simulation. A lot of the older generation teach the younger what they knew. Patience and smiles can break it. And sometimes players like to roll the dice for no other reason than to roll dice.
Also assumptions, human beings in general, will immediately assume that if it's not stated, then it isn't possible. It is on the GM to make sure that all available details are there. Which again trains the players into asking questions that you might want asked.
Finally, patience. Not every one gets the same clues as you might. What seems obvious to you might not be to everyone else, and as GMs we need to realize this.
Also I personally take exception to being God as a GM. I am not. I build the world in broad sweeping strokes, place towns, events (aka Dungeons and/or Adventures as the case may be), make some non player characters, and then I let the horde of cats (aka Players) loose. And it is on them to do what they want. I will provide guidance and adjudication as the situation merits, but I run games for people. I do not run them for myself, I have my personal stories for that.
Besides, players will latch on the strangest NPCs. I could be here all day telling you tales of how players became fascinated with no name characters that were there for colour, loving them for the weirdest of things. I personally have learned to go with the flow of it.
In short, as a GM, I am a judge, rules arbiter and world builder, I may seem I have a lot of power, and thus wear the Viking Hat, but I am nothing without my horde, and it's up to me to be fair, impartial and if the case may be, on their side.
I apologize for this bit of a rant, but this is a bit of a pet peeve to me. And yes, I am likely blowing it out of proportion, but it's to make my point, not to pick on you. Apologies if it seems that way.
