Prime Minister Forever
At least it isn't called Paul Martin Forever. Another 21 days of him will do me just fine.
For the political junkies out there (you know who you are), here's probably the most detailed simulation of the upcoming election you're likely to find. You control one (or more) candidates and manage all aspects of the campaign, from policy to ad buys to spin control and dirty tricks.
I was fooling around with it yesterday afternoon and it looks quite well done. Of course, it depends on what weight the designers give to intangibles like "leadership" and "integrity," but that problem is common to all strategy games. You can download the demo from the CBC website, and get a coupon for 20% off the $18.95 price if you purchase it that way.
The demo allows you to play out only the 2006 election, and you can't vary the computer players' strength. The full version covers elections dating back to 1993, allows you to edit or run alternate candidates (including yourself, if you like), and has a scenario editor that can model situations from ancient Rome to the futuristic.
The company also has versions for American, British, Australian and German elections, all for Windows 98 through XP (they'll also run under Virtual PC for Macs).
