Cool city, but wish there was other things besides the tourist attractions.
Many great cities have an awesome balance of typical touristy things to do, but also have either an obvious nightlife or other activities they are known for. The only things to do in Roma are sightseeing and eating the fantastic food. This is of course simply a cultural difference. The Italians appreciate art and food.
Insider Tip:Plan ahead what activities besides sightseeing you want to do. They'll be difficult to locate while you're there.
