My PS+ subscription expired right while I was near the end of Mass Effect 2, so I'll have to renew some time at least to finish that game, I haven't been happy with the value that I've been getting from PS+ with just the PS3, but I now have a PS4 :-) so I might have to reconsider... It's become very expensive though
