Let's list out some pros and cons:
Pros for GM credit, especially repeated credit
•Incentivizes GMs, especially experienced GMs, to run more games
•The more often you GM a scenario, the better you get at it.
•Allows GMs to bypass those annoying and dangerous low levels. (Don't want to lose that Rat Folk boon to a lucky crit? Have a concept for a Magus that's pretty much unplayable until 4th or 5th level? etc.)
•Makes scheduling easier if you don't have to worry about avoiding duplicate scenarios for your GMs as well as your players.
•Makes it easier for GMs to keep their characters up with the pack, especially when you're re-running scenarios for new players that your experienced players have already played through for the second or later wave of new players.
•GMs don't have to be as strategic about where to apply credits, if they apply them now, they'll still be available later if a character really needs it. (I don't want 15 characters with 1 chronicle on them, or 5 level 2 characters that I've never played. But I might want to apply a chronicle to one character to bump him up to level 5 so he can play in a 5-9 a week later some day but, if I've already run that scenario, no joy.)
Cons for GM credit, especially repeated credit
•Unlimited replay is Bad, we know from experience.
•Incentivizes GMs to farm specific scenarios rather than a broad range of scenarios. (Everybody knows that, after the first time you schedule a certain season 3 trilogy, you'll be inundated with requests to repeat it for at least 6 months.)
•GM credit gets boring: You're not playing your character but he's still advancing towards retirement.
•Paizo gets less money.
•GMs already get enough rewards from stars and the fun of seeing different groups solving the problems in different ways.
•GMs can choose not to take credit when they run a scenario, saving it for later when it would be more useful.
•Lack of repeated credit is only a constraint in a small set of circumstances: GMs who have run a LOT of scenarios, scenarios with boons, venues that only run a subset of all available scenarios.
Some of these are paradoxical or resolve themselves:
•GMs get better with practice|Replay is Bad: First, we have to ask, why is replay bad? Players can spoil plots, or hang back too much in an attempt to not spoil the plot. That's not a problem for the GM, though, in fact the opposite is the case. I don't find this persuasive as applied to GMs in general. GMs can get bored of scenarios and just phone them in, but that's an individual issue and certainly organizers should be able to handle that along with other problematic GMs.
Another problem is farming for gear or boons. I never experienced Living Greyhawk, so I don't know the havoc it caused. But again, from the GM's perspective, we already suggest GMing for exactly this purpose. How many threads asking for a list of boons are answered by "if you want it on a specific character, just GM it?" Frankly, though, I have no idea how much of a problem this would be if there were unlimited credit allowed for GMing it, since we effectively have unlimited runs available due to multiple players potentially wanting to GM something for a boon. I think this would boil down to an individual issue again.
•GM credit allows you to level a character past the boring spots|GM credit gets boring after a while. This boils down to personal preference. Is it more boring to you to play through level 1 on a character that can't really do anything, or is it more boring to have characters spring into full bloom halfway through their career? Limiting unlimited credit to tier 1-5 scenarios addresses this somewhat, but I think the deciding factor really should be "Who am I to tell you what you find more boring?"
Interesting. I'm still not entirely sure about "•Unlimited replay is Bad, we know from experience." How is this based and what is it based on? Is this just your opinion? From another game? I'm actually extremely interested in learning. I think I have asked 3 or 4 times already with no answer. There are only a handful, really, of examples in PFS, and well, they tend to be, as far as I know, the absolute most played and purchased scenarios and modules out there, (even after discounting that most of them have been free).
•GMs have to be careful about taking/wasting credits|Gms can choose not to take credit when they run a scenario. Unless I misremember the Guide to Organized Play, the latter really resolves the problem. If you don't have a character that you want to apply this specific chronicle to at this time, then just don't take the chronicle and you can pick it up the next time you run it. I've almost completely stopped taking chronicles unless I have a specific use for one: The last chronicle I took was in August in order to bump a character up to level 7 so he would be eligible for the 7-11 I was scheduled to play in the next week.
Hum, I'm not sure that's true. If so, nice to know, though. I was under the impression you had to apply it immediately, and a more recent change allowed you to apply it to a 0XP character (getting a max of 500GP, 1XP, and 2PP). Something to look into just to know.
All that being said, I think the last con really is dominant in this situation: Lack of repeated credit is only a constraint in a small set of circumstances. I don't think the situation is generally broken, and this is one change that will only affect a small subset of people in specific circumstances. It's not an unquestionably positive change, so I think we should hold off on making any changes until the issue becomes more general. This, of course, it colored by my experiences so others might be having more problems with it that I've seen.
Again, interesting. I'm not assuming my opinion is the best one, just wanting to hear all the different sides. I'm personally unsure if such a rule would actually make Paizo more or less money overall, kind of thinking it would mostly be about the same, but still thing to consider.
Why limit this to Tier 1-5 scenarios?or
If we adopt this, how long until someone wants to expand it to Tier 3-7 (and so on, and so on...)?
We have unlimited for Tier 1-2. Tier 1-5 is the next (and would it also count for Tier 1-7) in line right?
Not sure if I should read this as "the sky is falling" or not. My intent in limiting the hypothetical proposition to 1-5/1-7 was because in my personal experience matches up well with the overwhelming majority of what I hear from others, that those or the Tiers most played and requested. 3rd -18th, not so much, though it's also a lot more difficult to find GM's for higher level play in general.
But, honestly, (and Im not actually "advocating" this, mind you), outside of specials and a certain 4 parter, what would rally be the harm in making everything grant GM credit each time you run it?
