Quoted from dr_nybble:The idea of a "campaign mode" is intriguing, where you would achieve goals over many plays, accumulate trophies, etc.
Imagine a D&D style game where you gained experience points for your character over multiple plays and unlocked new scenarios. And kept your magic items!
Saving a regular game would kill longevity.
An online ever evolving campaign would be awesome but probably would cost way too much money for too small an audience.
