I haven't played the fifth installment much lately, but among all the castles, the human one appealed to me the most; it's quite beautiful. I've played as everyone except the dwarves (and I haven't played as the Hammers of Fate at all), but the human castle is simply gorgeous. However, I'm a fan of the third game, so my opinion might not align with those who love the fifth game, perhaps because of the graphics. While the graphics are good, judging by the replay, I expected more from the game, specifically from the creatures, but all the castles are beautiful!
