Playing Heroes of Might and Magic V on Ubisoft servers.

yes
What kind of jerks are on the Heroes Union forum? Nobody plays, they create a bunch of maps, and nobody joins them.

So, here's a suggestion. Check out the online topic on the mentioned website for a detailed description of how to play Heroes 5 online, how to generate maps using the alternative map generator IRMG, and a description of a map for a tactical duel HRTA, and so on... And then you can try your hand at this tournament. And by the way, there are no jerks here... :D
