whats your favorite generation of Pokemon?

Its not even a contest. The first generation, by far. The others can't even hold a candle to the original 151. The others aren't bad, but I feel all the best ideas were used in Red/Blue and everything else was just an afterthought. 
 
Wait, do you mean Pokemon games or actual generation of Pokemon species? Either way, its Red/Blue.

i like silver/gold 
the new pokemon weren't that great but it introduced the day and night cycle and breeding which was awesome 

" i like silver/gold the new pokemon weren't that great but it introduced the day and night cycle and breeding which was awesome  "

Well when talking about game i would say gold/silver but when talking about when the show was good I'd say red/blue generation

Gold/Silver are my favourite games, though nothing beats the original 151.

The first two. Classic mechanics, classic Pokémon, classic times m8s.

Third gen, ruby and sapphire were amazing games. Sure I spent a lot of time as a kid playing the first 2 generations but they just haven't held up over time. Terrible artwork, broken leveling systems, very basic battle mechanics. Ruby and Sapphire made the series more complex and customizable and looked great visually. I've spent more time on Ruby alone than I have on r/b/y/gold/silver/crystal combined. 
 
4th gen morphed me into a competitive player but I did not like Sinnoh as much as Hoenn, just not as memorable. Also there were only TWO FIRE POKEMON species in the entire zone which was a bitch.

The original generation might hold the most nostalgia value, but Gold/Silver are good too. The pokemon that were introduced in G/S may not have been as good as the original, but it felt like a solid expansion upon them. G/S also added a bunch of new features, and there were 16 badges. Every generation since Gold/Silver/Crystal has felt like a rehash though, and I really haven't cared about the new pokemon.

Red FTW!!  once they moved on from 150 pokemon thats when i left.

Everything after the first generation is weak.
 
It's like the ran out of ideas and just started slapping two weird concepts together.

Wait, are we talking about best generation in terms of the actual Pokemon or are we talking about which games are best?
 
Screw it, I don't even care.

The first generation is the only correct answer.

I choose the original Digimon... But if I HAVE to choose one of those.
 
Nothing will ever beat the original 151.

silver/gold. It had new pokemon and it had the Kanto region.

I liked the first two a lot, but I think silver/gold wins by just a little.

platinum

red, blue, yellow were the best pokemon ever. the other newer pokemons were getting bad. they kind of ran out of ideas i think with the pokemon. they all look the same now.

The first one. I mean.. COME ON. Those original 151 were the absolute shit. None of these other newbies can compare...though I do love me some ChimChar.

Ruby and Sapphire for me.  I've played them all and was a kid when Red and Blue came out.... but Ruby was REEEEEEEALY good.  I mean how can you beat Secret Bases???  That's right... you can't.

thats a tough choice.. cause the originals and the gold/silver ones are just amazing.. but i think gold/silver>red/blue>>>>diamond/pearl>>>>>>>>>>ruby/sapphire

I'll go with B.

Red/Blue/Yellow. Obvious for anyone who really likes Pokemon.

Red/ Blue/Yellow, largely for its Pokémon being far and away better than the newer ones and also for its great game design.

Gold/Silver/Crystal. Duh. Probably the only generation to add wide-sweeping changes to the franchise for the better (i.e. not contests), and the creature designs still didn't suck. Those who say otherwise probably never got past Red/Blue/Yellow anyways.

First. Shouldn't even be a debate.

Gold Silver. I was so happy when they remade the games.

#1-#150, *maybe* #151. They basically dominated my entire third grade year. 
EDIT: So Red and Blue, then.

" The first generation is the only correct answer. "

In actual Pokemon games or the Pokemon themselves?

" The first generation is the only correct answer. "

The first generation was the most original, and the best. The second generation wasn't that bad, either.

Red/Blue/Yellow.
SIlver/Gold are a close second.

E: The one where they all die like the dinosaurs did.

In terms of games, Gold is still my favourite out of the rest.  I've tried playing newer iterations of the series, but I can't get into them.  In terms of of the actual pokemon, the original 151 will always remain my favourite.

gotta say the classics.

After playing Soul Silver I'm surprised how much the series 'evolved'. I mean sure fundamentally it's very similar but I must say I like the pacing of Ruby and Diamond much better.
 
I'm picking Ruby over Diamond though, the weather changes due to the legendaries made them feel more 'legendary'.

There have been some interesting Pokemon that have come out in the later generations, but they are diamonds in the rough. Originals are still the best, but I can appreciate the desire to expand the number as people get used to the current ones.  Its just a shame that for the most part new ones are just re-hashes of old types with new faces.  Granted its not like they can introduce too many new types, but different faces on the same team of 'types' doesn't really make the new generations any more fun.

THE 151 FIRST POKEMON WERE THE BEST.

blue is what got me into pokemon (and gameboy in general) but silver, for me was my favorite and longest lasting pokemon playthrough

First one is the best but i can stand the second one too.
Fuck the rest.

" The first generation is the only correct answer. "

The metal generation. Ruby/Sapphire just couldn't live up to it.

Getting Pokemon Yellow the day it came out when I was in eighth grade is one of the greatest memories I have. I spent the next week getting Haunter and dominating the Elite Four with him. Good times...
