Homeworld is my all-time favorite game. It reminds me of my favorite boyhood picture books-the Terran Trade Authority handbooks by Stewart Cowley. In fact, now you've got me wanting to knock off early and start a new game. It's been a while, and even longer since I played multiplayer (incidentally, my screen name here is my old online Homeworld handle, "Jackboot").
I am currently playing the camapign for the 100th or so time but I never get tired of it lol. I am currently in the Gardens of Kadesh where I do my best to capture the multi-beam frigates (they make life Oh sooooo much easier in missions like Bridge of Sighs and other tought ones).
I would LOVE to play multiplayer but WON.net was replaced by Valve's own Steam so it does not work anymore. :( I did play multiplayer before though.
Hammerstrike is the screen name I always used in Homeworld. Named after a missile system from another game I like called Heavy Gear.
