Here are some RP ideas that are in my head currently. Feel free to add suggestions that tweak the plot or suggest a new plot completely. Also please note that all names mentioned in these suggestions can be replaced. I am just using them so it is easier to write the description for the RP.
A Death in the Family
The Howard family was a successful one. The father of the family was a successful lawyer, while the mother was a stay at home mom who cared for her children deeply. They had 2 kids, Marcus and Marissa, both prodigies in their own right. Marcus joined the Marines after he graduated from college, and Marissa went on to join the FBI. All of this came crashing in on the Howard family during a robbery where both their father and mother were killed. It's been 20 days since the robbery, and no one has been able to find him. Will Marissa be able to stop Marcus from using his skills that he gained in the marines to seek revenge on the people who killed his mother, and quite possibly save his life in the process. (I would play Marcus. Marissa can be a guy BTW since this will not be a romantic love RP)

Coming Back To Earth
Keith Bishop was once a modest, humble, and dedicated high school student. This was all until he joined the basketball team and his success went to his head. As one of the top NBA and college basketball prospects in the U.S.A Keith was living like a king, and he acted like one too. This is until his best friend from elementary school transfers to his High School, but she is not the same as she used to be. She is the only girl that he can pay attention to even though he could get mostly any girl he wants. Will she be able to change him back into the person he was before his new found success while still advancing his career, or will Keith be another case of someone who couldn't handle their ascension to fame?
