A lot of mid 90s stuff aged pretty badly I feel. Perhaps my perception is selective but quite a few movies, songs and games from the mid 90s that I enjoyed back then don't really hold up too well. Although I guess there were great movies like Pulp Fiction, terrific timeless games like Terranigma and some good songs I can't come up with off the top of my head as well. Maybe it's really the combination of being from the early 3D era + mid 90s, both of which I think are unfavourable circumstances for a product to age with dignity.
A lot of us were kids or adolescents in the 90s (as was I) and I guess the fascination most of us held back at that age is hard to replicate.
OoT is certainly not among the worst or worse aging games of that time though. FF7 is in a worse condition really.
