I have been playing games for 30 years, the 2 most influential and memorable I can remember from the 90's were Tomb Raider and Mario 64, but from those 2, Mario aged better, I can still play it to this day with enhanced graphics on an emulator, on the other hand Tomb raider would be near unplayable to me now. Those were the 2 first 3d games I ever played.
There were others that also are very memorable, Metal Gear, Gran Turismo, Resident Evil, Ocarina of Time, Final Fantasy 8 (I never played 7 or 9), Quake 2, Command and conquer and many more
