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

The solution is to generate castles randomly + bidding for color and castle. This is, in my opinion, the most important thing to add to the rules, not to polish the details.

Suggest only how to implement bidding in SOD (don't suggest TE and other related things).
I only have one idea. Dismiss the first purchased hero, thereby giving a bonus of 2500, 5000, 7500, etc. But somehow it doesn't seem quite right...
