I'm going to have a kid soon so the liklihood of my playing multiplayer games that take hours is not going to happen.
So, I play single player.
The one thing that drives me nuts the most is that I could have thousands of gold ahead of my enemy but as soon as that thing ticks down to 0, the AI up bids me.
Its easy to get distracted if Im in battle or something. Setting some form of "max" bid would be great. Allowing me to bid and see hte status on the window at all times would be even better.
