And then there's that game that was originally Imperium Galactica III, but Digital Reality abandoned the project for some reason and it was handed to another developer, who turned it into a Homeworld-like affair rather than something resembling IG2. Forgot its name though.
It was renamed Nexus the Jupiter Incident or something similiar.

I'm a sad sob apparently.. :( i have never put much playtime on IG2 although i still have the game somewhere.. the even sadder part is i cought up on the hype and forgot all about it, and now IG3 is probably sleeping with the fishes never to be revived.. i guess i'll go dig IG2 and reinstall it again. But whats that about not working in WinXP?
