Strange Attractor@adrianmryan I have a fondness for Puzzle Pirates, which has been around for more than a decade. It can be played in the browser, with Java.
Depending on how you play, it can be casual, but there are parts of the game that require longer periods of time and interacting with other people.
It's free to play, though if you give them at least $3, they won't delete your character for inactivity.
