1. In game "games" in the tavern. So those on line could gather and play a hand of cards and gamble on the outcome and take each others gold! or maybe a wheel of chance, or a dice game, just as we would see if we had walked into an actual tavern full of smelly ole pirates!
2. More "adventures"; tasks to accomplish that help one along in the game (particularly for the newbies);
3. Any new game feature that promotes more activity online, ie being on line more often with player interaction.
