Hello p3love,
You lost me on the scenario card bit, but yes sometimes on VASL somethings are easier but in F2F and playing with the board and counters there are somethings you loose when you go to VASL, mainly perspective (in the computer world you have a monitor and you can zoom but your kind of stuck with the flat 2D images, with F2F and the 'real thing' you don't loose the perspective, you can move around the table, lift your head this way and that way and scan much better than any computer generated equivalent, in my opinion).
With ASL this is not a major deal, but if you take a more traditional board war game (say something small / normal out of a S&T or AH/SPI standard 34x24 map 100-200 counters) it starts to manifest it's self (VASSAL compared to having the map out and moving the pieces 'live' around) and then this is greatly exasperated when you move to the 'monster' war games such as War in the East, or any 2 map or 3 map game with 300 to 1000's of counters.
So those that say VASSAL/VASL is the better way is not always true, especially from that physical real life perspective.
Hope that makes some sense, it's sort of hard to explain, the better example would be to pull out said games above (if you have them) and then find a VASSAL / Cyberboard equivalent and you can begin to see the benefits of using the real cardboard over electronics. Of course one of the benefits of using electronics is leaving it setup forever or not worrying about dog/cat or child messing up the setup.
As far as the face to face interaction I have always been going on about, for me I guess it's would be like you can have a couple of pints of ale at your place alone with yourself or your pal is sitting behind his monitor having a pint, but the experience is so different if you and I went to a local pub with all the people around and we slammed down some pints together in person and started chit chatting about this that or the other thing.
Again, not sure if that makes sense but that is how look at things...
