Resulting from a poll held on Third Wire's forum, readers have decided that they want a WWI sim the most! So Third Wire has gone to work at it!
Here's the official word:
"Well, what I can tell you now is that it is a fun, light sim, and not a hard-core sim. Basically SFP1/WOV set in WWI. :) Any further news, details and updates will be made available here and on our website at approripate [sic] times. "
