Ok. Put it this way. If you had a 50:50 chance of every adventure you started ending halfway through the adventure, would you change your approach to gaming?
Yes; I'd find players (or a DM, as appropriate) with more of a sense of long-term commitment, and carry on from there.
And by long-term commitment, I mean things like intending to live in the same city for the foreseeable future, willing and able to stick to the game schedule as agreed, and not being flighty when it comes to always wanting to try new settings, systems, and so forth.
Fifteen adventures with the same characters? Dude, most people are lucky to get three.
You are so far outside the norm that of course this poll won’t work for you.
Why am I so far outside the norm, though? And, really, should I be?
The short-campaign-as-normal thing is IMO a direct result of WotC marketing* in the 3e era (and since), as short campaigns are extremely likely to lead to more demand for books and materials. WotC outright said, for 3e, that the game is designed to go from start to finish in 18 months give or take; and people took that to heart and (sadly) normalized it. WotC sold more books, and then watched and learned as Paizo refined the process into the single-path-as-whole-campaign model, leading to the current-day corporately-mandated "normal".
* - sure, some were playing designed-to-be-short campaigns pre-WotC, but I posit they were at that time the minority.
As for character career length: the benchmark for a character to get into our Hall of Fame is ten adventures. Including a few long-term adventuring NPCs, who we view as being the same as PCs, since 1983 we've put about 130 characters in there. The longest career in terms of adventures is by a character who has been in play on and off since 1981 and is currently in her 39th (!) adventure.
There is no “stance” here. I was accused of hating roleplay because I suggested that DMs speed up the game. The reason for the poll was to see if I was the outlier here. If most people felt they were successfully completing campaigns, then fine my advice would be bad advice.
Yes, and if I vote "nearly never" you'll take that as data to support your speed-up-the-game position, with which I disagree.
