Beyond fluent writing and the interest which one carries to military education Ender, this novel also marks the reader and the sphere SF by treating deeply visionary themes and with foresight. While in 1985 the Internet is just beginning his conquest of the world, OS Card guess already what could be its potential as part of the dissemination of information and networking in the multiplayer network game. Amazing!
Fortunately, Ender's Game is not just that these innovative ideas as it is more ... maybe not a "masterpiece" but definitely a great SF novel that one can not let go before to have read the end.
A human and military SF (not militaristic!) To suit all generations of players, aficionados of the genre or not.
