There are a heap of "educational games" for primary school students on computers and tablets. The only ones we ever found were particular useful were the ones who made rote drill a bit less painful, like those that gamified arithmetic and phonetics.

Senior school is a different story and my kid's school uses a lot of computer based apps for all sorts of things. However, English literacy generally isn't one of them; they're primarily for STEM and music (eg aural skills drill) and languages. Animation can be very useful to explore things like physics laws, mitosis, maths graphing, etc etc etc. There doesn't seem to be any shortage of these pedagogical products, but they're not ebooks either, and they're not there to make literature "more engaging". They are there to transmit information that is best transmitted by animation/video. Students still have to study printed words (or their accessible equivalent, if they have disabilities) just like they ever did.

What is your goal for this thread? What are you trying to learn and achieve? Your questions seem very unfocused to me, which makes them difficult to respond to.
