Based on your signature about ps+ and that you mentioned fps, I'm going to definitely say Killzone. It's on sale for $9 right now(see my signature).
Try Persona 4?
Toukiden in less than a month. Also, I would hop onto the 14 for '14 sale on the psn store and see if there are any games in there you have a question about or might consider. I got 5 games for $23 yesterday.
