Zombies on PC

With the amount of zombie games in the past year, plus the announcement of more to come, its led gaming sites to believe there's a zombie invasion going on right now. But truth to the matter, Zombies have been with us in gaming for a very long time. In fact for various platforms (via Moby Games query); 2008, had 8, 2007 had 7 zombie games, 2006 had 7, 2005 had 9. 2004 had 6, 2003 had 7, and on it goes. To think Zombie games are on a insurgence, is just ridiculous. If anything, gaming sites and developers have run out of ideas.

Here's a list of great Zombie games/series from the past:
SSI Gold Box Series (ie Death Knights of Krynn)
Resident Evil series
Blood series
Thief: The Dark Project
System Shock
The Typing of the Dead
Left 4 Dead
Plants Vs. Zombies
