I like the idea of being able to continue playing after winning the game. The only problem is that the dungeons do get a bit old pretty fast.

However, if D2 supports this function, please... please... give it TCP/IP support. After game play in the battlefields it would be enormous fun if you could have a friend or two bring their characters into the battlefields for some team dungeon crawling.

Just make sure there is no PvP allowed... that always screws up a game and leads to massive cheating.
