Yes, granted, Ender's Game has that slightly young-adult feel that I find characteristic of many of Card's books, but it's no less enjoyable for all that. I very much like the descriptions of the games and the Battle School. Moreover, child-Ender in Ender's Game is (at least for me) a much more sympathetic character than teenager-Ender in Ender in Exile.
I was surprised to find that the introduction of Mazer Rackham and the entire battle with the Bugs takes place in the last 60 pages or so. I remembered it happening much earlier, but my brain misremembers things like that. (As I believe I definitely proved when I reread The Diamond Age by Neal Stephenson.
Anyway, still enjoyable, and I'm happy I took it out of the library.
