While not exactly a wargame, this title has me intrigued. It is called Software Inc. I watched several hours' worth of video, and this appears to be a pretty deep title. I have three other versions of various software company development sims, and this looks to be as good as any of them.
This link is safe..take a look, let me know what you think.
