Freelancer, really the space sim or 4x space sim genre in general, but the freelancer sequel was being developed and chopped. The kicker is it was being developed for the xbox 360, so it was only recently cut.
Not to be the old fogey like many of us on GOG are, but it does feel like innovation is being sucked from modern gaming. Why did homeworld perfect an innovative three dimensional RTS, and a true 3d rts unknown since (even SOSE isn't actually three dimensional). Is the turn based game restricted to only be developed in a Civ game anymore? Must innovation only be found in remakes or revives? Perhaps that is what we need.
