Mmmm, for me it's a toss up between UBW and HF. HF was so much better in terms of romance, morality, horror, and UBW was such an adrenaline rush of action, a clash of ideals...
I'm glad I got the True Ending the first time for HF... although when I got the Normal Ending afterwards I was so upset =/ I'm so glad that the ending I liked was the True ending, Normal ending in HF was just too depressing.
I'm trying to get all the Tiger Stamps so I can see some final epilogue, can't wait.
God dammit, why can't big Japanese publishers make a story this great, with all the resources they have, while a small company can make THREE awesome stories.
