Older gamers may remember a great ZX Spectrum game in the 80s: "Great Britain Ltd" Democracy is the 1st game I've seen pick up that concept for the vista era.
What I liked about the game was being able to be leader of many different countries - policies play out differently with the US electorate if you are president, and you will have to contend with policy obstruction if you lose either house in the midterms, and the differing start points of UK, Australian and US policies is good.
The game is very addictive - each time I've played it I've found 4 hours has gone by very quickly.
The interplay of policies affecting different interest groups and economic dynamics is great e.g. childcare provision plays well with parents, not so well with capitalists, but improves productivity which assists your tax income through rising GDP.
If the game has a drawback it is overly anchored to a single main screen so not too visually exciting, and it can seem that progress after a few terms is limited once you've implemented all the policies you wanted to.
Overall though, its great to see the genre reborn, and show bush and brown how to do it! Enjoy.
