I'd like to help you a little bit around the forums. Take note that you've used your very first post to tell the community that:
A) You have a game "in development."
B) You need someone to work on a completely original tileset and original sprites for your game
C) You didn't take the time to go back over your post and check for simple things like grammar and punctuation.
Don't be surprised if people aren't jumping on board.
Take my suggestions, and they are only suggestions, and try the following:
- Let us know which RPG Maker program you're using. It matters.
- When it comes to the title of your game, I'd suggest taking a look at this (http://rmrk.net/index.php/topic,29558.0.html) link. You may find it helpful.
- Post some screens shots of ANY work you have accomplished so far on your game as it may encourage some people to offer you help (I know you are looking for original artwork, but very few start with all out original stuff. So us what you've got!).
- I understand that you may have given your game's plot a lot of thought. However, it sounds a lot like a lot of other games involving crystals, wars, cults and magic. Perhaps you should think of something to make your game unique?
- Go to the Welcome forum and introduce yourself. Tell us who you are. You'd be surprised how that'll help.
