It is the lack of surprise cards.
I know why they don't exist -- coding the app to allow any player to play a surprise card at any point would be somewhat complicated. It would require allowing a player to have a "surprise" button they could press that could unwind a move and even as I'm writing this it is already messing with my head.
So yes -- while I understand why the online game doesn't have the "surprise option, it does make it less of a tactical game than in the real world.
You can't interrupt a user during their move, you can't prevent them from taking a keeper or an action card.
And you can't stop them from winning -- that is the part I miss most.
When another player whaps down a goal and goes "AHA!" and you go "Not today, Satan!"
It is still fun playing on line, however the lack of surprise cards makes the games a little too pedestrian to be as fun as they could be.
