Either 8-bit generation offerings from Sega and Nintendo or 16-bit generation offerings from Sega and Nintendo.
Looking at titles for i e Famicom (befor NES launch in US) in the beginning to the offerings at the end of that consoles life is staggering (just jump in on NES if you have Nintendo online and for example look at Twin Bee, Ice Climber or Donkey Kong and compare that to SMB3, Kirbys adventures, Journey to SIius or Blaster Master), same can be said about the Mastersystem.
At the same time look at SNES, while looking good from start it ended in primitive 3D-games, the jump is immense. Sega Megadrives offerings from the early days have not aged well graphically, but in the end of that consoles life time the games looked really good too.
