A lot of reviews on Freedom Fighters have been quite positive.
It's basically recreating the movie "Red Dawn". The commies have invaded the US, and you are just some joe schmo (like Patrick Swayze) that starts up a rebellious band of "Freedom Fighters". As you complete missions successfully you gain charisma points to help you recruit more fighters to your side.
It sounds really fun, and has got good reviews. I was going to spring on Tiger Woods 2004, SSX3, and either FF or Rainbow 6 III at the Toys R Us 3 for 2 deal.
