I really couldn't recomend FoF enough. It's an excellent play on platoon/company solo board gaming.
I remember I was looking for a Korea game and some people recommended FoF. I checked it out and was like "Nah ah"...not into card games at all. Then I took the plunge and honestly, every time I'm thinking about which game to play next, FoF is right at the forefront and the only reason it isn't constantly on there is because I need to play some other games I've bought.
FoF2 wasn't my fav due to the fixed terrain. I much preferred the first edition.
Rules are shockingly bad which makes the game seem so much harder than it is...I'd recommend getting the new rules set from the GMT Deluxe Edition website.
