Rating system for online games in Heroes of Might and Magic IV.

Or maybe we can do without a rating altogether? Everyone plays for fun anyway! And it creates some kind of inequality: some will be cool, others will be losers. Let's just play!

:) Not quite. Then why have tournaments? Players participate in them not only for fun but also to try to take higher places. And, accordingly, as in any other game, there will be winners and losers. So I don't see anything wrong with the rating ;)
