Great Experience
Takes time to get the hang of it, but overall its an amazing game to play and very addictive.
Missions are pretty hard to understand as you go along. I found that the Asians were easier than any other then the romans and hardest was the eqyptians, can't really remember why :P
Be patient with the game, during building process start off with 2-3 woodcutters, 1-2 saw mills and 1-2 stone cutters. Then try and move onto the grain farm, fishers hut etc then onto mines. obviously expand your borders to begin with by building towers then using pioneers after you've built your large residence.
Gameplay = Good
Graphics = Good
Worthwhile? Yes.
