Quoted from AbeVigoda:
I think the thing about RPO that people loved was all the nostalgia callbacks. Imagine that book without all the 80s references, just story only. Would you like that? If so, go for it.
Totally agree. The story is kinda "been-there-done-that," especially if you have seen The Matrix, Terminator, Or read Ender's Game.. anyway. But to put it together (it made me think of the Lego Dimensions game, if anybody's played that) was pretty novel
