As a long-time PlayStation player and PS+ subscriber, I can't say I'm really impressed with this offering. I mean, they're kinda hit or miss each month, but sometimes you get something that was surprisingly good (I really enjoyed Galak-Z).
Maybe one or both of these games will be good, but the highest Metacritic user score of the two is just 7.0 for Vampyr. NFS has just a 4.2.
