Is there a site that list all the computer wargames ever?

Guess what! There are at least two sites that list all the computer wargames ever.
Now, don't panic when you see them, they are old, as wargaming itself.

Web-Grognards
Connoisseurs say that if a wargame is not on Grognard, chances are no one considers it a wargame as well. They define themselves like this:

'Grognard' is slang for someone who likes playing wargames. 'Web-Grognards' therefore has a unique collection of various conflict simulation game (i.e. wargame) information, including (but not limited to) rules errata and variants, game reviews and links to relevant web sites. The emphasis is on board wargames, but miniatures, computer and card-based wargames are also covered. Many hundreds of games are covered here.

M. EVAN BROOKS HOME PAGE
Mr. Brooks stopped in 2002 but who can beat the quote on his site:

"It is well that war is so terrible, lest we grow too fond of it." -- GEN Robert E. Lee to LTG James Longstreet at the Battle of Fredericksburg (1862); obviously Lee never played PANZER GENERAL.

In case you still have doubts Mr. Brooks is a Panzer General fan, this is what he writes about it:

Initially marketed as a non-wargame, this has become one of the classics of wargaming, and spun off an entire series (ALLIED GENERAL, PACIFIC GENERAL, etc.). Start in 1939 and trying to win enough operational battles in order to successfully win the assault on Washington, D.C. (Ty Bomba would be proud!) But a plethora of scenarios, entertaining graphics and a user-friendly interface combine to form a winning combination. While I both admire and enjoy it, the military lessons of combined arms are not taught overly well, and often gaming logic supersedes military logic (for example, in order to win a decisive victory at Moscow, one must air assault north of the city; then, in following turns, one can recruit armored units in this isolated area and pincer Moscow from two sides until it falls).
