Have you guys tried roleplaying with your characters (multiplayer)?
Not necessarily through audio but with the game chat function at least!
- Comment on the events heard/seen on the TV/radio
- Build up a character personality through their occupation and personality traits and act on them
- Tell tales of what you have done in the game
- Discuss about several locations in the game world
- Go through future prospects, goals, fears...
I tried a little bit with one friend (the others weren't interested) with one line here there. Was fun!
With modded extra animations it could get even more interesting!
