Which learning method is more effective: traditional SuperMemo with questions and answers, or the new hypermedia SuperMemo with videos, games, puzzles, and tests?

Simple questions and answers are extremely effective and easy to create; however, some users find classic SuperMemo too boring. If the psychological factor plays a part, the variety provided by SuperMemo 8 may substantially add to the effectiveness of learning. The answer to the question will depend on the application domain and the mentality of the student.
