As far as people who are funpires, I second the bad DM complaint. By all accounts, a good DM is one who knows how to make a player's desires happen within the realms of what's plausible for that particular setting. A bad DM railroads hardcore, stonewalling a player the instant they try to do something creative. In my case, the DM had his reasons - the overall story was part of a school writing project - but his execution was about as subtle as rotting corpse.
Compare a good D&D session to any other good game's story: A setting is laid out, and the clues all point the player(s) toward a big damn goal, and off you go. With this kid, he basically said "this is where you're going, this is how you're getting there, oh noes this is taking longer than I though we gotta speed this up GET IN THE CARRIAGE!"
Actually, while I'm on the subject of D&D-related funpires - you're damn right I'm on a rant - when one of the other players has opinions that are so disgustingly opposite your own, and they're not subtle about it in the least. I've seen less stupid douchebag machismo in my all male field artillery battery than I'm getting from this one homophobic puddle of stale urethral discharge.
Now, as far as games being funpires, Major/Minor is the undisputed king of absolute garbage WASTED POTENTIAL fun-sucking. I could write an essay about everything it does wrong and title it "See This? Don't Do This."
For those of you not familiar with the title, Major/Minor is a visual novel that, in no uncertain terms, is awful. There are good VNs and there are bad VNs and then there's this, this underwhelming trainwreck of narrative and character logic, production value and good ideas gone to waste.
So what do I mean about wasted potential? Early on in the game, the player character meets what amounts to a god in this universe, and you're told that you'll be sent on an important quest, and you'll be given some measure of power to help you. This god character then says that time is short, and he can only answer ONE more question before you have to be sent on your way; the game promptly says Do you want to save your game? After you do, you're presented with four options for questions... but you just saved. You absolutely have the capability to ask a question, get some information, and then just go back to ask the other questions.
It gets worse. It doesn't take long before the player is shown events happening elsewhere, but presumably at roughly the same time. Plots are teased, diabolical intentions are made clear, and at one point, it's made painfully clear that some supposed allies are betraying the player character. Multiple times the player is made privvy to information that could potentially save lives, if that information is acted on carefully and cleverly.
Yet, absolutely NOTHING is done with any of this! The PC has no power, it was a damn lie from the beginning! The scenes being shown to the player is not for the benefit of making future decisions, because the decisions don't goddam matter, it's all the writer being deep in his own ass.
For real, folks, it's bad. It's beyond bad. I've made some poor buying decisions in my relatively short time on this plaent, but Jesus gross furry fetish Christ forking out $20 for Major/Minor has to be my worst. Without a doubt, the biggest funpire I've ever known.
