Clues not yet guessed:
#46 - Released as a 10th anniversary celebration of this JRPG series, the 5th numbered entry and currently last entry in the series (not counting a spin-off)
#45 - Kitty Kibble shortages and broccoli everywhere.
#43 - After swapping green lands for a murky city, this second sequel traded both of the above in for the desert. Featured a "wizard of oz" esque ending.
#41 - The final boss of this fighting game was a young woman who beared a startling resemblance to a missing character... who had been possessed by a phantom spectral wolf.
And here's a clue for my next one:
#39 - Third person shooter where you play as a police mech and fight "sky captain" in a bizarre but awesome base-defence game
