Freespace is one of the best games to rediscover after many years. I think the first time I rediscovered it, widescreen support was a new thing, and man what a difference THAT made!
I then rediscovered it a few months ago, and this time I haven't drifted away from it again, probably because of all the excellent campaigns. And I've started one of my own, even. Pretty great that a game like this is going strong nearly two decades later.
