I really would have no idea who the best 5 flash artists for '04 would be, but here is a few that I would like to recognize.
Psycho_Goldfish, synj (nice work on AH), Adam Philips, James Farr (fellow Canuck, w00t), the dude that did Fallen Angel, Mouseklilks (FFA+ left me roftlmao), Legendary Frog, IllWillPress, and TLF.
I don't care really who makes the top 5, just so long as it isn't somebody that all they submit is porn. ;) This year was a great year for NG, because AH is out, so is GISH, and all these indie games that show the world what indie games can do. Overall, flashes keep getting better and better, and so people are starting to rely on this media more to transmit information, and to shwo the world that geeks truly do rule. XD
