There you go. Since the PS3 support will be ending with the next expansion SE is doing another free upgrade campaign. If your sub expired you also get 2 weeks to play for free from the day you download it to play so perhaps you can save it for when you have a bit of free time like Winter Break. You also have until the end of next year to do so so you have plenty of time to decide.
I wasn't going to suggest much. I was just going to say since you have some games now to tide you over you should wait until some more major releases come out. Some ideas include:
Disgaea series. (If you haven't played any of them yet there is a collection of 3, 4, and D2 for $40) Comes out next week for PS3.
Dengeki Bunko: Fighting Climax(A 2D fighing game from Sega with a bunch of anime characters not from SJ) Comes out on the 1st of October for PS3/Vita
Tales of Zestiria(I don't think I have to tell you anything about this one.)
The Legend of Heroes: Trails of the Cold Steel(If you enjoyed Trails in the Sky you should enjoy this one) Comes out on November 17th for PS3/Vita.
Sword Art Online: Lost Song.(I think I remember seeing you mention that you liked Hallowed Fragment so I can't see any reason you wouldn't like this one. ) Comes out on November 17th as well for Vita.
