Not a bit. You'll get to watch the playing-out in your email, or on the board. And the level of secrets makes the playout so much more interesting!
If you're playing face to face and you see Russia and Germany go talk for ten of the fifteen minutes, it's no secret that they're working together. Online, it's much harder to tell.
The face to face meetings add another dimension with false signaling, too. Hey France, next round I'll talk to Germany and get that army moved out of there for you...
Oh man, the emotional investment in this game is just never replaced by online play, imo.
