Impressions of Heroes V, for those who have played it.

I actually liked the 4th installment; I could play it for hours (days). The gameplay was very captivating. I really liked the independence of the heroes. And all the races were roughly equal: today I'm in a lyrical mood, so I play as a nature race; tomorrow I'm very angry, so I play as Inferno. Well, and if things are really bad, I play as Necropolis.
After playing the 4th game, I wouldn't go back to the 3rd. And the 5th game is like Heroes, but not really Heroes.
