I found that if you are good you seem to get alot more game experience, because when you are evil the game is to easy, Eg on the last japanese island you can fireball the nearby armys so its alot easier to complete the level, Also the easy way to level your archers on that level is to put dem on...
Well if ur evil just build hundreds of skyscrapers lol, it doesnt matter if your evil its only if you are good you should worry about skyscrapers, I recently went good so i dont use skyscrapers anymore :) so i recomend you use Skyscrapers for a evil god and villas and manors for good gods :)
yes you have to buy the rest home from the tribute menu, also i dont have BOTG's yet so i cannot answer that :S sorry but ill be buying it soon so ill try help you out. :)
What you should do with your old people is to make a rest home for them :) or pick them all up with the multi pick up and BURN THEM!!! but thats for evil gods only
I recently began a good god save on B&W2 and when my population got up to 200+ i had around 30 breeders all male because female...
I once heard there was going to be a multiplayer for BW2 but i havent seen one :help
Also how do you become good because no matter what i do my creature goes evil and destroys the enemy troops and that makes me evil :S
