Which Game?

Hello everyone, been awhile since i've posted a blog. Been busy with life and such but I would like to say hi to all that I've left behind here at GS. Anyway just writing this blog to figure out which RPG to start playing next. I'm causually playing The World Ends with You on the DS (which is a delightfull game by the way) and I've finished playing MGS2 (which was amazing). Now I'm just debating wheather to start the Shadow Hearts series or the Shin Megami Tensei series. So let me know your thoughts and suggestions as I'm itching to play either one of them. Good to be back.
