I like battlestar galactica online as well. Dj Kleen said it right you google and then BAM you're flying through space lol.
This coming from the "picky guy"....I have yet to find one - lemme say - a GOOD one. I recently tried out Battlestar Galactica Online -- yes, it's free. Yes, it's being promoted commercially by SyFy.
Flip it into Google and BAM - You're flying in Space. Overall - if it's a time waster you're looking for (and can really play games at work) grab yourself a small portable TV and hook up a PSOne - have a Smartphone that can run Emulators (SNES Super Tecmo Bowl FTW) or ----- try a site like http://www.rpgbrowser.com.
I am unsure about free ones... but have you checked out the Darkspore Beta... its free until April 22nd.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
