The Making History website now offers playable demos for Making History: The Great War, Muzzy Lane's World War I strategy game. There are demos for the Windows and OS X editions, which can be found on the game's website and on Steam (thanks Frans). And for those who already own the game, a new patch is now available which adds a new scenario in addition to fixes and tweak. This page has the patch notes (formatted upside down with the new notes at the bottom), and here's word on the demo and the patch:

Spread the word to all your friends who need to try before they buy -- we have just released a free demo of TGW ! For those of you already playing you now have access to a new scenario: "The July Crisis." Set in 1914 just prior to the Austrian Archduke's fateful ride into Sarajevo, TJC will highlight the difficult and very different decisions you will make depending on which nation you decide to play. The demo begins in the same time frame as the full length scenario but limits the number of turns and only Austria-Hungary is playable.

These are just the biggest features in what is otherwise a huge update including many fixes, AI improvements and content additions. For a detailed look at what's new, check out the latest RELEASE NOTES.
