FtB is fine if that's how you wish to handle things. As a "great man" once said, you decide your own level of involvement. If however you like to play with the details and exercise your imagination there, then that can quite easily be fun as well. RP is a thing you do for fun, not every action has to be about character development after all, or even a planned development of your character. It could just be something you want to do, ERP or otherwise.
