Storyline, Articulate, et al. Developer and Voice-over talent...
Character and narrator voices...yet add making new courses and updating older courses from previous or ancient, obsolete software...and finding fixes to make those course updates to work in a LMS.
There's also the other side - composer, singer, musician, published "short-short story" author, playwright, actress, (performance) poet, animation and video creator...oh yes...was a Elearning training instructor and helpdesk analyst.
The fun of making courses is multi-fold...to make your clients happy with something fun, interesting and memorable in a good way...and the development.
Truthfully, it's always fun. :-)
