Vizzed Board offers thousands of playable games online like Newgrounds (newgrounds.com) but actually has professionally made games and retro classics from the game systems like Nintendo, Sega, Game Boy, Atari, Apple II, Turbo Grafx, etc - way more than what Retro Uprising (retrouprising.com) offers and you don't have to download anything or install anything, all the games are played in browser like Kongregate (kongregate.com). Unlike Mini Clip (miniclip.com), the Retro Game Room offers awesome games featuring popular game series like Mario, Pokemon, Sonic, Zelda, Final Fantasy, Mega Man, etc and uses top of the line online java emulators for it's online game roms like VNES (virtualnes.com) and NES Cafe (nescafeweb.com). All games are no longer being sold but I will remove any copyright violations upon request.
