Was wondering which guilds do you build or consider absolutely useless.

Me? Usually play english so1-2 archer guild.

I always build a merchant guild in capital to increase $$ from trade and merchants.

and usually just 1-2 each of spy,assassin,theology guilds.

have never been offered horse guild.

find explorers guild useless, but will build 1 just in case.

rarely get weapon guild

every other city gets merchants.
