I'm starting to wonder if it's a fear of finishing.
This is different than work. It's something you love and want to be great. Part of the joy is working on it...so that immediately has negative repercussion if you finish it. It's a passionate thing, and I think you are having a natural struggle.
Like this whole NAP thing has had a real chilling effect on me. I mean, hats off to the guys who contributed, that's some great game design and some fun scenarios. No shade from me there. It's the negativity; the rejection of a whole chunk of the community implied by the title. Like, when I first got into the blow-SR and reading the reviews, the stuff that was carrying this hobby forward was artpunk. Reviews on this very site put me onto stuff like DCO and the wild experimentation coming out of LotFP. I myself have shilled for Luka Rejec's trippy UVG. I'm sorry that people's personal politics are conflicting, but S3 is hands down the best thing ever written, fight me. The weird is right there in the foundational DNA of the game!
I think you need to take a step back and realize that the OSR was founded by a bunch of folks (@DF, right?) that were protesting against the dominate game-of-the-day, i.e. 3e/Pathfinder. They felt (and I agree) that looking at adventures written for that system was completely alien, and not at all the hobby they enjoy playing. That group is never going to embrace anything except the game they love---it's in the "charter" if you will.
What more, I am very sympathetic to (us) OD&D/AD&D folks having a niche on the internet that can unabashedly say we think that the early version of the game was in fact also the very BEST version of the game. There is no greater joy for me than seeing some of these B/X-file Europeans (like Prince) slowly realize that AD&D is actually a superior/advanced game, and witnessing a glacial migration away from "D&D light" towards the "real deal".
That's just a personal vindication/pleasure. But just because some old-timers are entrenched with their classic game is in no-way the same as thinking we (lazy) graffers are going around, kicking in doors of Pathfinder forums, and screaming insults around wildly that your late editions "suck". We are soooo smugly confidence, insular, and bunkered at this point, there's no reason to sell or crusade against later editions.
Like the shear vitriol and intolerance coming out of some of these crusty old douches is so depressing.
To be honest, this I haven't seen. Only folks I seen worked up is over about thinly disguised politics (e.g. "woke" cancel-culture, blow-back from knee-jerk "nazi-branding", and other cool-crowd hit-job attempts).
Prince has some of the exuberance of the "newly converted", and combined that with the Dutch's tendency to announce their opinion loudly and his generally joy of internet combat---NAP posturing is the result.
NAP is not explicitly against 3e (even if it does exclude later editions, that's tertiary). NAP
is against style over substance. Full stop. "Artists" tend to get wrapped up in appearance/innovation, while historically D&D was played by mathematically minded, fiddley, war-gamers. These two groups have very different ideas about "fun". NAP is simply saying you don't need to be flashy to be good. What more, if you are all fluff, Prince is going to point out there is no substance to what you are selling. His claim is that it's all about PLAYING not BUYING/READING.
It's an honest point. And if you are into churning out flashy 'zines/adventures that do not hold water---you will most likely be hurt by it. (And let's be honest, art-types are far more socially attuned to criticism than traditional war-gamey nerds.)
You in particular are a fish out of water in an around the NAPsters because:
a) you are a visual artist
b) you traditionally have really enjoyed consuming products that have been aesthetically exciting but also slightly impractical for real gaming (e.g. Planescape).
c) you play a later edition
What to do?
To please yourself, your adventure has to be usable for the game you play (3e), that few (if any) in this small Bryce-Prince-Melan review circle/cult is going to appreciate.
To please yourself, it needs to be exotic and wild (genre-bending). This is anti-NAP because of the rules, but not anti-OD&D.
To please yourself, it needs to be visually impressive (allowing you to use your professional expertise). Again, not anti-NAP...so long as there is clever game-able substance to back it up.
The only problem is going to be if you need the opinions of others to justify the effort. I suggest that you should not. You will be happier if you make the adventure to scratch your personal itch and ignore the world.
I say this as someone who is dropping (intentionally) useless art weekly on the internet. I do it because I feel compelled to chase that muse and I enjoy sharing the results even if it noiseless goes "kerplunk" into the void. I want to make something that I'd love to see---even if mostly it's something only a parent can love. We are driven to create for our mental health. The act of creation is a thousand times more rewarding than consumption. It's as simple as that.
Don't justify it. Artists are generally not appreciated in their lifetime. Don't let the lack of a target-audiencet stop you. Just make something you think is awesome---ultimately your opinion of it is the only thing that matters. (i.e. It will never make you rich or famous---that was porno/artist Zak-Black's thing. Did I ever mention that his name is on as producer of the latest
Frazetta book?)
