Well, I played T3.5 and I really enjoyed it, than we got T4, basically travian legends and I stopped playing, because its crap. My friends stopped playing aswell, but when we found out, that there is travian kingdoms, we tried it and I think its great with only one flaw, the amount of gold you spend is absolutely ridiculous.
Govenors and kings are just great, leader is true leader with advantages. For govenors its friendly if you are begginer. You dont end up as farm in first day after protection ends.
