It depends on what you think is boring. Starting as the child king is hard, because you have 2 starting counties (Paris and Orleans), the Bourgogne has a strong claim (which makes no sense IMO, because he is a cadet-branche), the duke of Champagne usally hates you and support the Bourgogne claim, Flanders wants independance and you have a very powerfull duke of Aquitaine and a lesser powerfull duke of Toulouse as vassals. Winning the support of Aquitaine does the trick, but eventually it bites you in the ass.
For a interesting gameplay you can of course try to claim Normandy back if William wins, expand your royal domain and strengthen the French crown, like what the Capetians did in history, break up your powerfull vassals, play with the pope, go crusading, play with the HRE by supporting revolting vassals, help the Spaniards in their reconquista, or invade the HRE, because you have lesser holdings than the HRE.
