Now here's something different yet addictive.  There's an action/shooter game based on Stargate SG-1 coming later this year, but what would you say to a Stargate simulation program?  Over at SGCSim.com there's a nifty little Flash-based program for Windows that casts players as a technician for Stargate Command and requires tasks such as opening the iris for friendly incoming travelers, dispatching SG teams to familiar planets such as Abydos and Chulak, and sending M.A.L.P. probes to unknown destinations.  Maybe you can even find the secret command to dial Atlantis in the Pegasus galaxy.  It's a free download, completely unauthorized, and definitely worth checking out if you're a fan of Stargate.
