Stars! was great!
Newbie info eh? Well if you've done the tutorial you've pretty much got all the major rules. Everything else (and it's a lot of "else") is just extra info. The manual has a few pages of new player tips in the back...
I dunno.... what more exactly where you looking for?
P.S. If you are interested in MP play no need to slave away at SP for longer than you want to... there is usually a newbie game starting every week or so and blitzes happen on the weekend.
