In medieval ages, there were carnevals(also called fairs if i spelled that right), which were popular among people.
Guilds actually got cheaper. Before they were 1 free then + 10 + 20 + 40 = 70 for all - with only 4 guilds. Now 5 guilds cost 50 diamonds in total. If 1 remained free, all people would use travelling fair free, thats why prices changed.
I'm sorry tiger but thats just not true. I can't see 1 reason why the hell i would use traveling guild on.
You would say because i can set higher taxes but that's wrong. Higher taxes gives you more gold but Craftsmen Guild gives you 10% on PRODUCTION.
I don't need more gold i need more wood !!!!
Now tell the truth. almost EVERYBODY use Craftsmen Guild and that's the reason why you change the way guilds works. In rare situations people would use traveling guild to repair moral but still the MAIN guild would be Craftsmen Guild.
Same goes for attack and defense. You use it when you need it. Not always.
