I disagree with that guy in the videos you posted, I think Colony Wars was an awesome game.
Oh yes, he does not know how to play the game properly.
Colony Wars does have a lot of flaws though. It was good for its time and it has a place in my heart, but I don't think it would appeal to the Freespace crowd today. I could just imagine the deluge of criticism about "bad FREDding" if those missions were running on the Freespace engine. Colony Wars Vengeance stamps the majority of those flaws out though and is just an all around superior game improving on the original in just about every way. That's something I'd be a lot more comfortable recommending people to give a try.
