Yet another late response to this thread, but anyway, I first thought I'd share my opinion of BoFA. I've had the game for a while. I got it for no other reason than because I thought it looked cool. I have been reading through the rulebook all week, and I must say, I am impressed. The game mechanics are simple, and I so far have been able to grasp almost every single concept in the manuel. In addition, the rules also add a sense of realism and a feeling of true mass combat. But truth be told I haven't actually played yet; I'm eagerly awaiting to, but first I must paint the armies. Speaking of which, it may seem daunting, but its not so bad--so far.
Now, @ GildorPl, Games Workshop barely supports this game at all. It is undoubtedly the least supported game of all the specialist games. Now, that's not necessarily a bad thing--as the game is not constantly bombarded with new rules updates that continuously require you to fork out extra cash to keep up with ''legality''--but its also not necessarily a good thing, as almost as soon as blister packs came out for BoFA, they were discontinued. There were minis for Goblin Guard, Gigantic Bats, Spiders of Mirkwood, Hill Trolls, a Storm Giant, Smaug, Elven Cavalry, and Dwarf Archers, but they are no longer availible. If you're interested in expanding your BoFA forces, Copplestone Miniatures produces a range of 10mm Fantasy minis that bear uncanny resemblence to the inhabitants of Middle-earth, and with a little imagination, Warmaster minis as well most historical armies can fit your needs nicely. I would assume.
There is only one detailed scenario, but there are multiple scenario suggestions included in the rules manuel. Then of course you can play points matches. I don't think you can get easily bored unless you continuously play the game over and over in a short period of time. Like any game. Yes, you can use minis from Warmaster; same stats, same size. You can have them represent armies from Middle-earth, or heck, with the Warmaster Fantasy, BoFA, and Warmaster Ancients rules being so similar, it would indeed be possible to see how Middle-earth Orcs face off against Warhammer World Greenskins. At 10mm scale, minis are very versitile in what they can represent. Finally, the stats included in the rulebook cover all of the following: Elves, Elf Archers, Elf Cavalry, Dwarfs, Dwarf Archers, Men, Men Archers, Eagles, Giant Bear, Wizard, Hero, General, Goblins, Goblin Guard, Hill Trolls, Wolf Riders, Wargs, Spiders, Gigantic Bats, Storm Giant, Dragon, Bolg, Goblin Chieftain, and Goblin Shaman. There are also rules for Bard, Gandalf, Dain, Thorin, Beorn, and Thranduil, which are slightly modified versions of some of the previously mentioned units.
If you are still in the dark, I would recommend first going to "Rick Priestly's Warmaster Website":
