Per another person's request, I will attempt a down and dirty overview of Kings of War. I have to offer a disclaimer in that I have not played them yet. I would welcome input from anyone who has played the game to jump in and comment.
KoW is a mass fantasy wargame written Alessio Cavatore, formerly of GW. The game certainly shows some WHFB influences but does have its own departures. The game is described as "simple but not simplistic" by Ronnie Renton of Mantic Games.
Individual basing is the same as WHFB, but the unit is dealt with as a whole for movement, combat and removal, so you can run massed individuals or a big single diorama base according to your preference.
All of the standard High Fantasy races are represented. You are welcome to run any minis you have, provided you fit them into the existing lists. For example if you have an army of centaurs they might fit into some cavalry based Kingdoms of Man list; if you have an army of Lizardmen they might fit into Orcs or Goblins, depending on your take on that race.
Armies are aligned Good Evil and Neutral. Anyone may ally with Neutral, Good and Evil will never ally.
Emphasis is on unit coordination and conventional melee or missile fire. There are no deathstars or uber heroes. Magic plays a secondary role for the most part, and is not particularly deep or complex. There are noticeable complaints that magic is too minimized.
Compared to WHFB, the game is very streamlined and rapid play. The game very much lends itself to quick pick up games on one hand, and clear cut tournament settings as well. The game strives to eliminate cheese and min/maxing.
A new edition will be available soon, adjusting some game play and points allocations. The present rules can be downloaded here for free here: link
There are TONS of write ups and youtubes on the game. Here are a couple to start with if you are interested:

I enjoy their forums. Very friendly, helpful, and a lot of sound questions, advice and perspectives. Mantic actually interacts with their fans and feels more like a company made up of gamers than of suits. manticforum.com
