Yes it is odd, this is the first FOG game I have played. They appear to be very well supported, with an excellent forum. But there is a real reluctance to issue a QRS and the errata was slow to come. Maybe since the 2 supplements are now done, there will be more focus.
I did use the Quick Play sheet to play my first game, but I did have to resort to the rule book quite a bit.
I have had a look at the yahoo group unofficial QRS that I referred you to, it does appear to be inclusive, but I have not gone through it carefully.
The ruleset is basically quite simple, but you can layer on a lot of complexity as need be. I like simple rules, with one step mechanisms, I am really much more interested in the strategy rather then the details.
I really like the command point function as it really makes you have to think about what you have to do.
I am hoping to eventually get to play more, but my gaming partners are few and distant (>500k), so it is difficult.
Good luck with the rules and please report back.
