Eternal Blue.

Congrats on beating the hardest RPG I've ever played (attempting to finish it again right now - last time, I just didn't have enough Silver Lights/whatever and my levels were to low to beat Zophar. And you're stuck on a forward path after you beat Ghaleon, so you can't go back and develop your party further. It sucks).

Well, I thought it was kinda hard, anyway .

I try not to rent RPGs, because I don't like having to deal with a time limit. I think the only RPG I've ever rented was Breath of Fire IV, but I had no trouble bringing that back after one rental period.
