Which games should go get this Fall?

If 2007 ended right now, the level of PC games released would already top the medicore heights of 2006. But the game industry really gets revved up in September as a flood of PC titles hits the marketplace and doesn't let up until sometime in early December. So which games coming out this fall are we at FiringSquad most interested in checking out? Well you happen to be in luck, my friend, because we have a handy list of our top 20 PC games we are most excited about playing this fall/holiday season (along with a few honorable mentions). Some of these games have taken literarly years to finally come to stores after their initial announcements (one game took 9 years, and we don't mean Duke Nukem Forever) and combine that with some of thes titles taking avantage of DirectX10 and we have the makings of what could be the best PC game line-up in years..
