Ugh Why am I put in this situation its like choosing either a brownie or Ice cream
. I really Like them both but I would say Ocarina of Time cuz IMO it has much more replability to it and without Ocarina of Time you wouldn't have Twilight Princess. Plus you gotta think in the context of the times graphics wise and at the time Ocarina of Time's graphics were like the Twilight Princess graphics of today. Its a slim and a hard choice difference but I think that OOT>TP.
