I've seen Song of Blades and Heroes (SBH), from Ganesha Games, on the street for a while, usually associated at a post on Tabletop Gaming News. I've always kind of discounted it due to the really cheap looking cover. Heck it looks as bad as some of those original D&D cover art. Compare for yourself. So it was with some trepidation that I plucked down an entire $8 on a PDF version of the rules while being board out of my skull one evening on my last work trip.
What I found was a really clean, simple to execute rules set for a generic fantasy gaming. In a nut shell, each figure on the board has two stats; Quality and Combat. The Quality goes from 2+ to 6+. It is the number you need to roll on a D6 to activate the model this turn. Combat is your martial skill and is a single roll up of your offensive/defensive/armor/weapon/skill/etc. It ranges from 1-5. One of the unique items I like on SBH is the activation system. When you choose to activate a model, you roll between 1-3 D6. Your choice. For every die that comes up on or above your Quality level, you get an action. If you get two or more failures in a single roll, then your turn is over. This forces the player to decide how risk averse the are... Roll a single die for everyone and you will get to activate everyone, but be very limited to only a single action. These actions walk, jog, run, attack, powerful attack, shoot, etc... each take 1-3 actions. If your only rolling that single die, then you can walk up to your opponent, but you won't be able to attack him.
On Saturday night late, after I had the green light, Eric came over and we tired a quick game. He had a small undead hoard with a Wraith, zombies, skeleton warriors and a few archers. I had an orc list with a warlord, 4 warriors and 4 goblin archers. What really struck each of us during the game was the importance of the leader's ability to make your Quality better while in the Long range. Eric's zombies had a real problem being Quality 6+ after his leader left them behind.
They have a quick and dirty mini campaign that can be completed in a night once you get the rules down as an average game is suppose to be about 45 mins long. Ours was a bit over an hour, but we did keep looking up stuff to make sure we got it ok.
Another great feature is that you can build your army as you like since they have an online warband builder that allows you to create a custom warband. So break out those Warmachine or Warhammer figs and get to building boys!
Finally, the seemed to have expanded past Fantasy. They have both a modern gun centric game using the same core rule set as well as a Napoleonic skirmish game which might be interesting.
