I think I felt that, too, though possibly such intense training would work to mature a child sooner.
For me, I found
Speaker for the Dead a much, much better book. The "trick" behind
Ender's Game seemed like it should have been obvious to anyone who ever watched the original
Twilight Zone. Overall, I thought it a pretty thin novel, but it would be hard to recommend
Speaker... without someone reading
Ender's... first. That it remains a major s.f. novel for so many people, I suppose indicates I'm just not the audience for it.
