I absolutely love PC gaming, but as far as consoles.. I would have to tie it between the SNES and PS1. I truly feel those were the days when gaming was more experimentation, rather than set in more rigid frameworks. There are of course exceptions to the rule, and games are evolving, but you also had radically different games in the same genre. There was Saga Frontier, Final Fantasy, Seiken Densetsu, A Link to the Past, Contra: Alien Wars... It just goes on and on. Of course there is still experimentation within the indie scene, but it just doesn't feel the same. Maybe it is just age.
