Though you seem really ambitious and bright, I doubt you'll have much success with this project...
My main issue is about the 3d, If you don't have any experience with it, this project will be far beyond your reach, why don't you start working on smaller games first? Try making a 3d version of Pong for example, that should be tricky for a beginner. Scrap that, if you can't program, start with the regular Pong first.
Don't expect you'll be able to recreate a working Engine anytime soon, take a look at essentials, people have been working on it for years now, and it still isn't complete.
I really don't want to discourage you, but these would, in my humble opinion, the best things to do for now.
Either stick with unity, drop this project, and start with something simple (trust me you don't want your special grand project falling into pieces)
Or switch back to RMXP.
best of luck to you ;)

P.S.
I know this message might sound a little harsh, but trust me, I've been into game-development for quite a while now. You'll get there, but you have to take your time and master the basics first.
I've been into game development for 5 and a half years now, so I know what to do. Trust me, Unity was my second engine. RPG Maker was my first. I know what to do when it comes to making 3D games. Just not the 3D Scripting Part :-(. (Actually, I know a fair amount, so I could quite easily make a version of Pong.) That's why I'm looking for help. And everyone, I've already got it. I would like to welcome Karel_Kazuki to the Pokemon Steel Team. He'll be helping with the scripting duties. He's new to C#, but has a fair bit of knowledge, and so, he will hopefully prove to be a great asset. He may also be helping with the composing duties now and again. Welcome to the team!
Also, replies to the other posts:
@Raymond (Hikari): Cheers for the kind words. It's good to hear the game is getting support.
@ppooookkkkkkk: Cheers for the tiles. They will be used for the terrain in the game. As well as more modernised, and incredible looking ones. PM them as soon as possible. Also, it's not RMXP. It uses Unity 3D, a completely 3D engine.
Okay, you are clearly intelligent from the way you write, but there are several things that don't quite sit right here.
For starters, what on earth is going on with your images? The stripes/squares in clashing colours is difficult to read and looks absolutely horrendous. I can't really say anything else about it, but it really makes your thread look a lot worse; you'd be far better off without them.
You also make a lot of claims without seemingly being able to back it up. You claim to offer a 3D world but can't make models, or write the necessary code. And you say that there are no stats or levels. Why not? And what are you replacing them with? And what are you actually planning to do yourself?
Finally, it's a small point, but offering somebody an exclusive banner for working on the game is a bit silly, and by no means an incentive.
You seem bright but very naive. Learn some skills, be it pixel art, 3D modelling (I can put you on the right track there if you want) or C#, and make progress yourself without relying on other people, or else this won't get off the ground. Consider scrapping your more extravagant plans initially until you have done some of the groundwork.
I knew someone would come up with that kind of reply. Sorry 'bout the images. They will be redone soon enough. I will replace them. Listen, alright, I'm not a Jack Of All Trades. I'm best being a designer, and am an average Pixel Artist. Not good enough for making a game on my own. Maybe silly little ones that are really poor and offer little fun, but I can work. Also, I am actually an above average programmer, especially with C++.
I'll tell you what the Stats and Levels are replaced with; Friendship Bonds and Mood. If the Pokemon is very happy, and is in a good mood, then they will battle well. You get the idea. Also, Nature Values. Nature Values are basically how well the Pokemon can battle in the environment. Different Pokemon battle better in different environments. Example; a Beartic would to amazing in a Mountain/Snowy Area, but will do average in a grassland, and appalling in a Volcano. Also, there is a battle-thirsty meter. If the Pokemon is hungry for battle, then they will battle with passion and power, and therefore, will likely win. If the Pokemon doesn't want to battle, then it will battle poorly, or even ignore your commands if you have a low friendship.
I'm going to start with the basics of the game. I can't work on the game without it. So, without further ado, I'm going to begin work on the game. I have prepared a huge plan document, fully ready with details.
PS: About the Pokemon Steel Team banner thing. It's not really silly, and they don't have to have it. I just want it. Too be honest, I will still have it, even if they don't want it. It just shows how much they care for the game. If they have it, they treat the game as an important game. They don't, then it proves they think it's just another game that will be special 'cause it's 3D. Well, I'll prove the people that think that wrong. You watch me do that. I could do it now if I wanted too. But I take planning first.
