How does it make sense, when the vision from the get-go was for it to be single player? There are plenty of party-based role playing games that do not have co-op and this one is no different in that regard. Just because a reviewer might think it would make more sense to have it does not mean that he should take points off for it being something other than what he wanted personally. As he is paid to review for the masses and should be as objective as possible.
In essence, the target audience for this game is people who love single player action role playing games, and if they read reviews that have points knocked off just because the reviewer wanted multiplayer, they are going to read it as being completely opinionated and worthless. Not every game has to have multiplayer and they should not be knocked for not having it. Especially when it was never the focus to begin with.
As far as new game plus goes, this game has it. But for the sake of discussion, let's say that it was not included. Things like that can of course be put into the written review as something that the reviewer felt could have added to the game's longevity even more, and he would be right. But if the overall game itself still offered plenty of content and was quality for what it was, then it should not reflect negatively on the game.
