The video game industry is an ever-changing landscape. It has its times of soaring peaks and its times of horrid valleys. But no matter the state of it, the video game industry is always changing, and with that change comes innovation and invention and sometimes even re-invention. Certain games set the bar for all others that will follow. Those are the games that will be remembered as the titles that gave birth to some of the best ideas in gaming. So in no particular order (and realize that this is by no means an all-inclusive list) here are ten of the games we thought were innovative in their own right and in some way changed how we play games.
