It features a Message Board much like Newgrounds, and also has a "Photoshop Portal", which seems to be a play on words from the "Flash Portal" of Newgrounds.
Retrogade is pretty much the same thing as Newgrounds, except there's less people, and still pictures.
"But wait, have you deposited your experience for Retrogade, reviewed some photoshops, and posted on the Message Board there?"
DirtySyko: Sweet! I need a break from NG.
-TheBhudist-: Yeah, I'm great at Photoshops!
Retrogade has a very rich history of ups and downs.
Founded in 2004, it was based off of the popular website Newgrounds. Except instead of flash movies, it was intended to be for art. It drew in a community of about 1000 users. A very small community who became very passionate for Retrogade and it's user-base.
In 2007, the website started to suffer. The upkeep for the growing website soon became the downfall. The website died due to lack of funding and the user-base disbanded. Some stuck around Newgrounds however finding a full-time programmer was an issue.
Now 2011, production has been full-steam ahead. The ground work of the forums and design have been established.
