Well lets just focus on AI as a comparable criteria. Would I prefer jumping on monsters that move in completley predictable paterns as opposed to combating with multiple animies which ajust their own attack depending on the strategy I choose to pursue. And that's that the begining of this gens AI.

Hmm...choices choices. 

4, although 5 was very close.

 Games now are not equal to game back then, back then things like depth of story and free roaming world were something new, today these things don´t impress me as much as back then, all these better graphics and sound don´t impress me as much bacause they are a natural developement, games back then had something much more important: personality and personality goes a long way, is timeless and cannot be improved on.

If you had two kids, lets say they are twinns, would you like the pretty athletic one over the one with personality  ??? 

 So, games don't impress you now as much as they did back then for no discernible reason except "personality" (which is an intellectually lazy argument if I've ever heard one). How is that not nostalgia again?

I'm not even touching the bad analogy.

The bolded part is the importent one, games will always look sharper and have better sound, but the things that really matter were already done a long time ago, if todays games had their own improvement (or their own personality) I´d give them credit for it, but the large majority of game just takes what was allready there and adds shiny new animations... thats not better thats just lazy...

I sayed personality because games back then made up for their technical disadvantage with creative ideas, style and intelligence, some games today may have that as well but most don´t or just badly copy the great games that already exist.

The older generations focused on quality over quantity since they didn't have much else to work with. I'd say the 5th generation was the greatest for many reasons:

1. It introduced 3-D games on home consoles allowing gameplay quality to increase multiple times over along with better interaction with the game.
2. The quality of sound in video games finally came into a realistic standard instead of just beeps and whistles.
3. Arguably the greatest games of all time came during that era and redefined many genres that even todays and back thens standards cannot touch in terms of innovative and revolutionary. Nintendo alone made games very popular and revolutionary with a lot of new series and ways to enjoy games, but games were 2-D before Nintendo came along. It wasn't until the PS1 came into being where games really started pushing the terms quality, innovative and revolutionary.

Bump

so far SNES,
had the best games I grew up with

PS1 since games on PS1 + N64 were very good.

I'll bump this since people are still voting.
