Agreed, the simpler the system the easier it is to play around with. Also I'd say don't be afraid of making up rules/dice rolls on the fly when players ask for something not covered in the rules, or if it is covered then you can't remember it. Nothing breaks the flow of a game like stopping to...
It's a good point but those people that I personally know in this self same thread and have mentioned that game will have to be in possession of a copy of said book....
Just saying :)
