Favorite Sci-Fi Series? (Video Games)

Okay, so the title is pretty self-explanatory. What is your favorite Sci-FI video game?

For me, I mine is what I beleive, a way underrated gaming franchise that deserves more popularity: The StaFox Series.

I believe that this series has much more potential peopel credit it for. One of them is famnous, but that is the only that gets appreciation, StarFox 64.

But it got famous since at that time it had revolutionary new gaming features, gameplay, and graphics. It was one of the games that first introduced rumbling controllers. Like I am saying, it only got famous for it's features, hardly being appreciating for the uniqueness of the games.

There are more games to this series and a new one will soon come out to the Wii U.

So what is your favorite gaming franchise? (that's Sci-Fi. Mine is actually Zelda, but we're talking Sci-Fi games here.)
