I named 4 Sim babies after members of one of my favourite bands. As toddlers, they mastered the toy xylophone. Once the reached childhood, the attended music school at the theatre. As teens, I bought them each an instrument for their inventory and they took the appropriate class at the theatre and they all signed up for music class after school. At first, they got wishes to play their instrument in the park and earn $25 in tips on their instruments etc. Now, they are being automatically given level 6 skills on multiple instruments, and getting wishes for ALL instruments. They only need to play the one.
Oh, um, wait. The keyboard player in the band is an excellent guitarist and often takes a turn behind the drum kit. During this time, the drummer usually takes over the bass but sometimes the guitar. The bass player actually had a hit playing guitar in another band whose bass player's father walked on the moon. He's also been know to take a turn on the keyboards when the keyboard player is on the drums. The guitarist, played keyboards on many of his solo projects and toured as Steve Hackett's bass player. Maybe the game is psychic and the above rant is inappropriate.
