Broke down and bought it tonight. Gameplay is enjoyable. I'm a total sucker for underdog games in general, and I don't mind a nice hack and slash with some RPG elements. This reminds me of Viking, with built in co-op and an interesting story.
Some weirdness... there simply isn't enough animation in a lot of what is going on. It's not like frames are being dropped or there is slow down. Animations just aren't there. For example if you are swinging your sword around, and then start to run, eventually the CPU just decides you don't need your sword anymore and it disappears from your hand and is sheathed. C'mon.. even Two Worlds I had a sheathing animation. I don't normally notice these things, but it's prevalent to the point of distraction. Similarly the first "boss" fight, against "The Beast".. "The Beast" is walking away from you, and the designers wanted him to turn around to face your characters, but didn't want to animate him turning around (?) so he goes from walking away to an immediately 180 degree facing you. Quite jarring.
That said, I'm having a ton of fun. Totally up my alley. Like I said, fairly Viking like, so if you liked that, give this a swing.
And yeah, in true Cheap Ass Gamer fashion you may want to wait til it hits $30.
