ITT things that can kill even a great game for you

>Have a really cool, attentive, and invested player
>Their character is well-developed and gets really deeply involved in the game
>Actively investigates on things and gets their opinion known
>Get well-tied to the plot as a result
>Quest givers address him directly
>Personally involved with the villains
>Important to the relationships of other PCs, even romances
>Gets little side quests during downtime
>Then suddenly he disappears without a trace
>Playing without him is nearly impossible
>Entire sessions are lost without him
>Ultimately keep going but it's not the same
>Half the plot crumbles because it had tied itself around this guy without me even trying
>The once so living world feels dead now and can never recover

This has happened to me more than once, and nothing over my entire time in this hobby has made me so permanently bitter.

If you're listening, Praetus, Ayla - fuck you.

Are you sure they're both still alive?

>great player invites friend
>player's friend is an absolute piece of shit
>worst roleplayer and an annoying asshole
>nobody likes him but his buddy
>kick him because he is making the game an absolute chore
>great roleplayer leaves in protest

Third Degree on all players.
NO! EXCEPTIONS!

This is even worse when you're the DM and a friend wants in on your game. You allow it thinking it will be cool to get a friend interested in the hobby, only for that friend to be the piece of shit that all your players hate, who shows no signs of ever getting better or treating the campaign with any more respect than a videogame.

Bonus points if he keeps bringing up "Why are you all so serious, it's a fucking GAME" as a defence.

Double Bonus Points if you're roomates with the asshole and kicking him out of the game means you have to hear bitching about it every day for weeks.

>Game gets to the level where the wizard can bypass almost every encounter or obstacle with one or two spells.

I have NEVER seen a system that includes multiple types of magic be able to work around this without resorting to sheer attrition to wear the casters out of spell-slots.

I HAVE seen a few systems where magic itself is limited in scope (magic can only summon elements, it can't teleport/mind control/shapeshift/ect) but unfortunately none of those games are popular enough to find groups for, and trying to apply those principles to popular systems like DnD gets a chorus of autistic screeching from retards who don't understand the game gets really fucking boring if the wizard can rewrite the rules of reality by level 10 or so.

Have you tried talking through it with your friend or explaining your players' perspectives, user?

Yeah, but he's one of those bro-dudes who keeps falling back on the "Stop taking it so seriously, it's a game LOL" defense and refuses to understand that even as a game it's more fun if everyone takes it seriously.

Ironically after kicking him from the game, he contacted everyone wanting to run his own game... which nobody has since shown interest in, despite pestering every couple of weeks.

Have you tried playing loud music to drown out his bitching, possibly combined with an obscene gesture in his direction?

Fuck you back.

You can easily restructure the plot to "Oh noes! This guy is missing! Possibly even dead? How will we ever possibly recover/go forth with our plans?" And pick it up from there.

>It's just a game
Man, if I tried that shit with hardcore football fans while changing the channel away from the Big Game, I'd get my ass kicked.

Just because it's a game doesn't mean it doesn't matter to some people.
