DISCUSSIONS on “Rules for online games in HoMM3 and formulas for calculating player rating.”

It's unrealistic to require everyone to stream. Many people don't have the ability to stream for various reasons. For example, if I'm playing from work, I have a daily limit of 300MB, and I won't be able to stay within that limit. Also, a 3G modem can only handle 2-3 frames per minute.

And as the experience of this tournament showed, mutual streaming doesn't guarantee that neither player will disconnect in the final match.
