I know that my friend's 20-something year old cousin that 10 year old me first played it with about a month after release was telling me it was "completely different and going to change everything". Now I find myself in his shoes. That's all my firsthand knowledge of academia's view of it. With my age group I remember it was about half and half, a lot of kids weren't all that into it because it wasn't fun enough or something? Giving me a break, the rest of us couldn't get enough of it. My friends and I were still playing campaign and multiplayer into the days of Halo 3.
