Well this world has been going for months now, the people here are generally fairly experienced with basic game play. If your looking for info on how to play the game there are some good guides that can be foundhere.
I would suggest starting on a newer world, if you are only beginning, say 50.
all game play discussion's are usually on tribal forum's.
discussing your fav nuke,fav d or your general tactic's here could be suicide really!
never under estimate the quality of people browsing for any snippet of info.
all the guide's as harb linked you too are well written and good starting point's........
