Yes - I'll probably do it when I hear back about approval. In the end I've gone for six topics, each of which will be considered within each of the two strands. It's a rather random selection and those that got in are not necessarily the most important ones, but perhaps leaving me leeway to do another semester's worth of this if I end up writing a ton more material than I need.
The topics I selected for submission are dictated perhaps more by the DH than the gaming side - for example, Travel got in whereas Gender didn't, despite the fact I think gender is a significantly more meaty topic to discuss from a game design perspective. The thing is that on a technical level, a lot of the problems you'd discuss in a Gender subtopic also appear in the Race/Ethnicity topic which is in there r.e. "how do you encode identity sensibly in a computer system". Travel meanwhile gives me tons of stuff to discuss from the technical side r.e. pathfinding and historical route mapping, and given I've actually worked on building a generic historical route mapping system I've got plenty to talk about there.
