France was my favorite in Castle Risk...... allthough I think Russia was the best in hindsite due to it's deep territory, and great location for a capital at Moscow which was 2 territories deep. I liked Castle Risk alot better. Especially the card system.
In RISK, I think the Best continent is America. 5 extra Armies with only three entry ways, while, the only other comparible is Australia, which has 2 with one entry way.
South America is a ripoff because it require the defense of 2 entry ways, and only yeilds 2 armies, and the worst is Africa or Europe.
My strategy is to play humbly, and try to pose as little a threat as possible, because I learned the first person to attempt early world domination gets hogpiled, and never has a chance.
