Actually I don't think you need ps+ to play, they had said it wasn't required before, at least I'm fairly certain they did, when the sub fee was still going to be a thing, but now that there is no sub fee I wouldn't be suprised if they changed that, albeit it dowsn't really matter because you probably have the service regardless.
