This thread was getting dangerously close to "flame war potential", but Ragnar has done a decent job de-escalating things to some degree. 

@Ragnar: I wouldn't say gender/reproductive identity is a political topic, but it is often politicised. This puts this challenge in a position of riding the line on the "no politics" rule. Please continue to be careful with it. If it does devolve into political discussions or a hateful flame war, I will need to lock the topic. Inviting people to commit suicide is not a good direction. You did apologize and recognize that, so thank you.

@Zombietom: If Ragnar is guilty of lumping you in with an undesireable group, it seems you're guilty of the same thing. Ragnar did not call you sexist or troll. He politely drew attention back to the distinct absence of a gender-specific term. Yes, it is clear there was a misunderstanding about what you were saying, but what you were saying was not super clear to begin with. Try to extend the same courtesy of avoiding negative assumptions you're asking of others. And keep the language civil, even in a disagreement.

@Ephesians: I'm having a hard time faulting Ragnar's conclusions about your intent here. The only thing I can think of that would explain away the apparent sexism or trolling is Zombietom's semantic argument, but that doesn't really mesh with your second comment about confusion over the meaning of 'non-traditional interpretations'. The options I can see are: 1) you're being semantic, 2) you're confused about the terms, or 3) you're being sexist/troll. If you're being semantic, you can't really claim confusion, and vice versa. I don't buy that you're concerned about what qualifies your potential submissions for bonus points after Ragnar explicitly said points mean nothing. Find a way to ask for clarification without being confrontational. Hateful behavior (like sexism) and trolls get banned.

Yeah, that trademark is so stupid. I'm sure your usage of them would be perfectly fine (monichrome or otherwise), especially since the plan is to have playstation be one of the available platforms, correct? The difference is your usage probably falls within the "fair use" mentioned by that disclaimer, but our hosting it on OGA under a CC0 license doesn't pass muster.

Regardless, Ragnar's suggestion is also solid (A, B, X, and Y... which cannot be trademarked) and buttons for them can also be found in that same pack.

Don't forget to include a link to your engine in the request! Seeing what you've got will help attract more artists. :)

P.S: Based on the logo, I was reading the name as "Tirna Nog" instead of "Tir Nano G". I assume "nano" for its portability and G for Gnu Public License, but what is "tir"?

Plenty of us can identify with your theme. It isn't a lack of understanding for what you're proposing. It's a lack of passion for a project we can't see. Like i said, most artists want to know their work will be put to good use. You haven't linked to any part of your project that shows this is different from the hundreds of other projects that said similar things but only wasted the artists time. YOU know this project isn't like that, but I don't.

I also understand having no funding for a passion project, but just change where Ragnar said "I want free stuff" to "I need stuff to be free". We know you're not greedy, but nothing else changes. 

No one is saying "I don't want to participate". But I'm guessing no one is saying much else yet either because no one can tell enough about it. Allow me to demonstrate the point I'm making: I'm offering you (or anyone who reads this) a job. Right now. No joke, I'll hire any takers on the spot. Paying job. EEOC Certified compatible with multiple types of anxiety disorders. Do you accept my offer? It's difficult to believe there is anyone who doesn't want such a great job.

You don't want to use free assets but you're asking for free assets to use?

I get where you're coming from, but the artists you're asking to work with you will have control over any content they create. Most artists working on a 'labor of love' project (aka not-paid, profit-share, 'free') prefer to release for free (non-exclusive) any assets they create for the project. I think you're going to have to decide which is more important; using assets that are free to everyone, or paying for exclusive assets that are unique to your project. 

Remember that using non-exclusive assets doesn't remove the uniqueness from your game. The things that set your game apart are the gameplay, narrative, how you are using the assets... not the assets themselves. Also keep in mind you browse game assets, but your players do not. Players don't care that they could download the assets found in your game. Well, some do, but they tend to like your game more because of it.

If you can't pay money for assets, you'll want to have something else you can pay with. for 'labor of love' projects, that's often the shared passion for the project. People can't see the vision you have, though. You have to share that passion, not just expect it to infect others naturally. 

Which is the primary purpose for this sticky post: https://opengameart.org/forumtopic/how-and-when-to-write-a-good-art-request

One of the more important points on the post linked above is:

"Have several hours of real gameplay.  This isn't just wandering around randomly generated terrain.  Real quests, real NPCs, real levels, boss fights, whatever.  The art can look horrible, but if you're asking people to work on your project out of the blue and you're not already established, you need to be prepared to show people that their art will be put to good use.  ... you just want to provide a good amount of gameplay to prove that you're dedicated and able to finish your project."

You mentioned most artwork is currently placeholders. Perfect! :D Use free art found here on OGA to flush out those placeholders and share a playable demo. A demo that looks like garbage will attract far more artists than a pristine looking game that no one is allowed to see.
