I remember Cam had hoped for a possibly more integrated solution, but in the meantime at least I'll get around to throwing this up o 3o; All the different sources for missions and similar stuff.
In contrast to DJ and Bounty Hunting missions, The Midnight Channel offers missions that may not necessarily include any combat, and are instead focused on interactions, including getting PCs to build social links with characters they're less familiar with. The Brave Arena, on the other hand, is pure combat, often a single PC against single/multiple opponents.
