surely not for an indoor scene? I think GI_Joe tends to make scenes boring and uniteresting. Most GI implementations dont give you any real sort of "mood" in the scene. And most people are too lazy to try and light a scene that evokes feeling from the user.
Take this scene above it could be made to look really moody and dark almost sinister by turning the lights down a bit and casting some strong, long shadows . Or it could be made really bright and sunny by upping the lights a bit, having lots of bounce light and some nice soft shadows.
GI is good for showing off a model but pretty crap for lighting a scene with any real purpose (There are exceptions to the rule I know but generally speaking)
