This is one of those great games. The board-game version (Risk) will be familiar to many readers, but the basic idea is this. The playing area is the world, about the time of the Napoleonic Wars. Up to six people can play at once. The game starts with the planet being randomly partitioned, with armies of the occupying player being put on them.
The object of the game is to either conquer a certain number of countries (playing for missions) or the whole world. You get a certain number of reinforcements each turn (more if you own a whole continent or two). You can gain extra armies by playing cards - when you conquer one country, you get a card. Trade in three cards for more armies - the number you get depends on the combination.
This version is a straight port over of the board-game, and the computer will play is less than six people are around. It's quite easy to work out how to play (the mouse is used almost exclusively). Winning is more elusive - you can be on top of the world one minute, only to be vanquished the next.
The game was written with AMOS, by Paulo Laureano. Graphics by Waddingtons (competently copied by Francisco Cordeiro). If you liked the board-game, you wil love this - I do! By far the best PD version of Risk to date.
