If you think Drama takes a long time to write, you haven't seen
anything yet lol.
You make plenty enough money off masterpieces without specializing in them. Masterpieces take a very long time to write and if you're playing with normal life span, you're not going to have time to write a lot of them. If you want to make any serious money from the Writing skill, you need to stick with a book that takes less time to write and do it in volume...so to speak.
Dramas are good for a main source of income. Once you achieve the "Speed Writer" goal, you can crank them out pretty quickly. But romance novels are a real gold mine, and if the sim is a "Hopeless Romantic," they can start writing them at level 6.
During the "Stop the Presses" challenge (that I didn't finish
), my author was a Hopeless Romantic. Near the end, she was bringing in $2 million a week, and had only written 3 masterpieces.
