I actually think it's a good idea to work on a game of a genre that he enjoys playing and knows well. Better motivation and knowledge. :) It's kind of like when you're starting out writing short stories or novels: easier if your first project is something you'd like to read.
I have to say that the only TD I actually enjoyed was Cubemen
, and that is a TD/RTS hybrid. Awesome game, though.
