Most of my latest GE projects make use of Pixel Art visuals which I found to work best for me. But I found that just like a Game Disigner pixel artists cannot survive in a vacuum, so I found this site called Pixeljoint which is full of tutorials, galleries and a forum.
I know Pyrometal had an account on pixeljoint but I don't know what his username was, but are there any active game editor users with accounts on the pixeljoint?
