The way I see it the abundance of legendaries and our attention directed toward them came when the Hoenn games did, and from that point on they've had somewhat of a role in the plot of each respective game. Personally, I wish it was like old times in which the legendaries were almost never discussed by people and the only details regarding them were hidden in journals inside of burned down mansions and such places.
The only real difference between genII and genIII is that there was a third uber for the third game
and the Latis.
Besides that its as similar as it gets.
When you play G or S, you meet 1 trio *bulbagarden.net image removed**bulbagarden.net image removed**bulbagarden.net image removed* and 2 true legends *bulbagarden.net image removed**bulbagarden.net image removed*.
When you play R or S, you can find 1 trio*bulbagarden.net image removed**bulbagarden.net image removed**bulbagarden.net image removed*, 2 true legends*bulbagarden.net image removed**bulbagarden.net image removed*, and 1 roaming extra*bulbagarden.net image removed*.
You know, 10 is more than 6 of course, but in Hoenn they were still distributed as evenly as genII, and for example Jirachi never even appeared as an ingame event, while *bulbagarden.net image removed* was actually introduced in FRLG, not RS, and was never specifically pointed to as a Hoenn pokemon if you get my point.
It didnt come with Hoenn, Johto had the first real legendaries. Its when they started being on covers instead of starters, so essentially right after a successful beginnng for the franchise............
Same with their lore. Gen I was the first, so it wasn't yet standing on firm ground. It was like Mewtwo, an experiment if you want.
Sure the amount of NPCs referencing legendaries has increased, but you cant deny that this was present from GS on, with people talking about the two mystical birds and the huge towers built just for them.
Not to mention genII brought us Eusine, the first person seriously obsessed with a legendary in the franchise.
DPt is the generation that actually really had a distinguishing increase in the number of "extra legends", and doing like double of everything thats usually covered once. The reason for this is that the fourth generation was intentionally full of awesome stuff, it was meant to be the ultimate generation.
Because of that, I was expecting that the number of legends would have went back down to 6-10 with generation V. But it stayed at 13!
So when you play B or W, you encounter 1 trio*bulbagarden.net image removed**bulbagarden.net image removed**bulbagarden.net image removed*, 1 true legend*bulbagarden.net image removed*, 1 roaming extra*bulbagarden.net image removed*.
lol.
Notice something?
Of course you find an enigmatic weak Kyurem*bulbagarden.net image removed* and can figure out how to get the extra Kami*bulbagarden.net image removed*, but besides that, the rest is not available.
Why is that? Because they stretched this generation into 2 sets of games. That's where the other new legends are introduced. Kyurem being the omfg true legend suddenly, Keldeo and Meloetta being revealed, and the roaming extras dont simply remain roaming extras, they gain completely new formes, EACH.
Genesect will probably come into play in BW2 sometime later too.
So my point in the last few paragraphs is that the 13!!! legendaries in gen V are justified by the fact that BW focus on the first half and 2 years later BW2 can introduce the rest.
But of course since we're all obsessed and check the new pokemon the moment someone rips and uploads them on the net, we see 13 legendaries and find it too much.
I agree with the fact that there are too many legendaries in the last generations. There are so many legendaries, that they loose their mythicalness. Before, each legendary was precious for gamers, now there are so numerous that they aren't as important as before. Moreover, the fact is that they aren't really interesting... I mean, we totally could have done without Thundurus, Tornadus and Landorus for example. They were already not very appreciated, but adding them a new form made them going down even more in my estimation, and I guess I'm not the only person. There are too many legendaries, and too many forms.
You have to distinguish between the REAL legends and the extras and events.
The true legends have been A FEW in every generation since GS. And all of them had the same kind of exposre and mythicalness. They been on the covers.
The extras, yes you can argue that they're too many, but do so for the DPt ones. Because Thundurus/Tornados in particular have a very specific basis, unlike say Cresselia or Heatran, who just represent interesting attributes (dreams and the moon, magma in general, in those cases).
What Im trying to say is, its not like they're just pushing endless amounts of legends into the franchise for the sake of it. Each of them has something unique and interesting about them, whether their origin, or representation.
