Play Warcraft 2 on your browser Play Command & Conquer Red Alert on your browser There's a bunch of other games, including Quake, Duke Nukem 3D, Carmen Sandiego, Ultima, pretty much all the classics. The same guy also runs online emulators for Sega, SNES, and NES. The java applet is extremely stable and the libraries are immense. I shared over facebook and figure I'd make a thread so the rest of you can enjoy these. My only wish is that it had multiplayer.
