NES - Non-Linear map design, and the ability to save in SMB3.
SNES/Genesis - Fatalities in MKII
N64 - Just the jump to 3D. Seriously, it was a massive change in games that will never be matched!
PS2/Gamecube/Xbox - Wandering around Morrowwind, and realizing that it was an entire game the size of a small country.
PS3/360/Wii - Watching everyone pull together to make it out alive during the final mission of Mass Effect 2.
PS4/XB1/WiiU/Switch - Jin's sad story from Xenoblade 2. Or realizing that NIntendo just made a better open world game than 90% of all open world games on their very first try.
