Another game you've probobly not heard of is King Arthur by Neocore, It looks fantastic, and seems to be being developed by a talanted and dedicated team, who know absolutly nothing about marketing. Serious I found this game by accident, there's no previews anywhere or anything.
Engine looks decent - a bit total war like, they've seemed to have gone a bit too much "wouldn't it be cool" for my liking, in that spells seem to pwn everything instead of the tactical skirmishing i prefer that you get with Dark Omen. Hopefully they're just showing off in the vids. The game is due to be released on the 24th, hopefully they'll be a demo on steam. http://www.kingarthurthewargame.com/main.html
