I only spent a little time in OOT, maybe three hours max. Everything is brown and I spent pretty much the whole time lost. In other words I give it the same review I give Goldeneye: for someone else.
That has been pretty much my experience playing that game, and I've tried 4-5 times to get into it, but just can't. I even tried the 3DS version to see if it was an improvement, but just couldn't get into it. In fact, until Breath of the Wild, which I thought was great, I've never been able to get into any of the 3D Zeldas. Granted, I've only tried OOT, Twilight Princess and Wind Waker, but they all had the same type of gameplay that I found more of a chore than anything else.
Everyone is talking about modding the n64...dremmel out the tabs....all that...all I did was buy a cheap ass sports game(NHL 99)id never play for about 2 dollars and put the back half of the cart onto sin and punishment. No cutting or anything needed. Just pop in the cart.
I did the exact same thing for the 2 lone imports I own, as I had a shitty All star baseball game that I got for free with the system and a dead Ridge Race cart. I guess if for some reason, such as bypassing rising US version prices, you want to play more than that, then it makes sense to mod the system itself.
