Why are you so critical of Heroes 5 and the anniversary edition? Yes, there are unfinished elements and bugs. But the game is excellent. Beautiful, captivating, and in the best traditions of the series. The only downside is the story.;)
Personally, I don't find it captivating. The graphics don't impress me, so I didn't notice anything particularly stunning. I don't like the music; in other parts, it was enjoyable, but in Heroes 5, it's better to play without sound. There's no map editor. The maps and battlefields are small, which means you can't fight the computer (which is dumb) for years (in-game time) to control the map.
