This has already been marked in a thread, but I thought I would give it some individual attention; especially with a lot of bad reviews from Arctic Circle. I stumbled upon this project fairly recently, and I am in no way a naval sim expert; however, this open source project is very stable and a lot of fun. As with any open source project the more hands in the pot, the increase for greater potential. It's currently in a second itteration release. If you google Global Conflict Blue the main page is a wiki (this is not a mistake). The most recent files can be found on this page and includes a patch. You must run the app as administrator in most cases or you will not be able to launch the app.
