yep its a large part of many games... :) largely they involve events they dont have to do anything (make them like 0 AC and not able to be name and maybe colourful wording or something) other then look good :) (make it sellable so people at least have a choice to do so) (not that i would)
on a side note... jon please implement trophy thing if you have the time... sure would make the game more interesting for many...
