X-Com is my favorite game of all-time, so I had to get Rebelstar. It's a fun game, very reminiscent of X-Com at times, and I totally recommend it, but it's nowhere near as good. You don't have the base management/research phase AT ALL, and you only control a few characters at a time on each map. Plus the maps aren't as varied or interesting as X-Com. Although I'm only speaking negatively about it, like I said, it's because X-Com is my favorite game. But I totally recommend Rebelstar if you can find it.
