I tried the "beta" and didn't like it much.
The gameplay doesn't flow really well, and the graphics look pretty lousy.
And I'm no graphic whore, I still play HoMM 2 and all sorts of classics (from the late The-Underdogs). And they all look better to me then this game.
Hopefuly, they'll fix the gameplay 'till release. I can ignore crappy graphics for the sake of good gameplay and lots of content (I just gotta get my hands around any Strategy title with skeletons
)
