Wouldn't it be possible to play Heroes IV online like this: you launch the game, choose from a bunch of available servers with the number of players, join any server, and end up in a large world where you start developing and conquering. That would be awesome... Is it really impossible to play Heroes this way?

Also, please explain. When I enter Hamachi, sometimes there are players with glowing green stars on the servers, for example, on the WC 2009 1-8 server. I right-click on the player and select "send message," write to the player, but they always remain silent. In short, everyone I write to when they are online doesn't respond... Why? Do they hear me or not? And also, when I double-click on a player with the left mouse button, a black window pops up with the message: "exchanging packets with 54.84.195.155, 32 bytes," and below it, the following appears: "timeout waiting for request." What is all this?
