Every country have all type of players, but tendencies form my point of view:
Germany - legendary donkeys
Russia - nobody knows what are they doing
Canada, UK, New Zealand, Australia - don't really care much
Ukraine, Bulgaria, Romania, Belarus - every cent matters
Japan - kamikazes
Norway, Sweden, Finland - always agro
Switzerland, Denmark - feel like they don't even know the rules
Argentina, Uruguay, Chile, Peru - angry ones (they seem to hate you every time they lose, so they take revenge by tanking and folding at the last second)
