nope, you played the NDS version in spanish, not the PS3 version.
these are two different games.
the NDS game has never been translated officially in english, a fan translation group did it. they just spent more time to do something for free for the fans, the spanish group just started translating it sooner.
Also,the companion book is not physical but included in the game, while the NDS version had a physical version of the book sold with the game.
The PS3/PS4 version of the game is slightly different. Yes, it's the same story, but not the same battle system. it has more cutscenes, different enemies, and different chapters than the NDS game.
I wonder if I'd better just buy the PS4 version again (I suppose it'll have all the DLCs), or play my PS3 original disc but without DLC. (I don't have psn on my PS3)
Oh, maybe they will release a pack 1+2? it might be less expansive to wait for the (hypothetical) pack. I don't have nnk2 yet, I can just wait and see.
