I had X-3 Reunion for 5 days then I sold it. It was ok I guess, but I found it too easy. In the free play mode, all you have to do is find one of the abandoned ships and you've got it made.
I used to own all 3 games..... I found X-2 The Threat to be my favourite one, it runs nice and smooth on an older system (which I had at the time) and it has an enjoyable (if short) storyline.
