As a big fan of Age of Empires series I have to disagree, after a while the game (even in hardest mode) becomes predictable and after that the solo mode game is pretty much done. That doesn't happens on a LAN party because humans evolve their strategies as their opponents gets better and that increases the life cycle of the game in orders of magnitude. Which would be a very important economical incentive for an on-line game. The thing is some research has to be done for this and the game industry is not very healthy to support research.
