If it's anything like X2, it's awesome. That game had some issues, but it was the coolest space sim I've ever played, hands down. It wasn't as focused as something like Freespace, or Wing Commander, or whatever, but that's what I liked about it. It wasn't just combat... there was exploration and a sense of scale and pace that hasn't been matched anywhere else, ever. I'd love to get into X3, but I just plain don't have the time.
