Games are for entertainment purposes, so if you aren't being entertained then no game has a point at all. If you're flexible and very forgiving, you will probably find a point to X-2, but it will most likely not be topping your favorite games ever list.

I had enough fun with it that I enjoy it. It didn't detract from X for me much. They feel so different when I'm playing X I just ignore X-2 even exists actually. When I play X-2 it feels more like fanfiction than a sequel, but I like it anyway
