Give things a twist.
Examples:
Eberron:
the sewer system is not overrun by rats because some CR 10 automatons do the cleaning down there. But now something has taken them over and they attacked their maintenance crew and killed some of them. The PCs are to investigate.
Vanilla:
Its not your orcs of the mill pillaging the surrounding farmland but e.g. devils/demons/giants whatever has the appropriate CR (and it might be odd for these mobs to attack lowly farming communities, what do they want / seek and why, is it some lost artifact or some special individual?
Dystopic world:
A la Darksun turned to eleven. The setting(s starting area) has almost no safe places, resources are rare to find, equipment is bad, support is low (only few temples stores inns etc. or none at all)
The whole environment is deadly because of heat / cold / radiation/ acid fog/ wild magic etc etc plus it is overrun with mobs which are to deadly for any adventurers lower than level 10.
Survival might be a major focus of that style. You might need some justification to dump the PCs into the starting area, maybe a la Ravenloft-mist-teleport does the job.
Hope that gives you some ideas.
