Heroes 6 - Discussion

You're thinking along the right lines. I can add that about 30-40% of the artifacts are based on artwork from the fifth installment. I also noticed that the heroes' names are a mishmash of names from all the previous games in the series. In some cases, even the city names are the same. I don't know, maybe this is a subtle reference to the previous games, but for me, it's more like a patchwork and a lack of original ideas.
