I have looked around and saw some real good spriters here, and thought, instead of asking specific people, why not give everyone a shot?
The game currently being developed is PokeRealms (signature link) and we are in need of good mature spriters (current ones are childish and getting in the way of other work). What we are really looking for is a custom tile set, custom pokemon sprites, and re-vamped NPC's (NPC's are a possibility at the moment, not sure yet).
If you would like to help us with this game and its sprites, please reply and show some of your previous work.
Thank you to all who apply and read the thread in advance.
(We will have a thread up as soon as I have 15 posts!)
Sorry if it is not specific enough, but the 'game' in Pixel Projects actually means like a fun activity involving spriting with the community and challenging others. It's not meant to be a fan-game or any developed game/ROM Hack. You can take a look at the Fusion Game thread as an example of what a simple but great game is.
I recommend you wait for those 15 posts by posting around, talk in some general sections, then try and get a thread in the Beginner's Showcase in the Game Dev section. Good luck.
