I'm surprised about your experience with BGA... Everyone I've played with has been nice. Some get a little touchy when you take a long time to take your turn, but tend to be forgiving if you let them know you're new/learning.
Yeah. I can't really explain it either beyond interface screw. One moment, I'm dumping my little villagers into the forest to harvest some wood, the next I can't do anything because the A) the space will accept no more people, B) I can't find the command to confirm my action, C) I can't find the command to cancel my action, and D) I can't do anything else but watch the timer tick down and ask for help on the sideboard chat before getting booted the moment my timer goes over. And this wasn't my first game of Stone Age either. There should've been no problem. And all the while I was getting a warning from my browser that it was blocking a pop up from popping up. I considered refreshing the page, but I wasn't certain that such action wouldn't have been considered me dropping the game in the middle of it.
