I just finished my first play-through of FO-NW, or rather I got to the final battle and lost interest, a lot of high points before that though. I'll give it a 8/10.
Apart from the bugs, and critical 'all save game wiping' bugs are pretty horrible to have in a final release...
I never managed to find enough cards to play caravan, at one time I even saw 4 full decks on a table and I couldn't pick 'em up.. I like poker so much more than blackjack, and why couldn't you play some of the major NPCs and let the outcome decide something important. Lost opportunity there.
