I guess it depends on how much data you store, and how quickly you need access to it. Relational databases are not the ideal format for mud-style data queries so you often end up with most of your data cached in memory anyway. They would reduce the amount of time you have to spend on working out file formats and the like, but if your coder has to ask you which is better, then I'm sadly guessing that they don't know enough about normalisation of data to be able to reap all the benefits of the relational data model.
