5 that's all you need per game. I'm not a Gen 1 lover but that's all you needed back then and now. There's no reason to have 10 legendaries. Myths and lore make a Pokemon. I don't need god-like Pokemon. I just need to hear rumors of a Pokemon throughout the game and encounter it by chance. Not for story purposes. That's what makes a legendary truly feel unique.
I only want a max of 5 Legends and I want each one to be as rare as it is to find a shiny. That would make it worth using. And get rid of hacks if worldwide trading is possible. Aahhhh impossible.
BTW I haven't found a shiny since the original Gold and Silver. That's cool with me.
I like tons of legendaries, but I prefer for them to be spread out, and hidden in far out of the way locations that are hard to find/reach. Not like the B2/W2 Musketeers. That was lame. I haven't even bothered fighting them yet because of how easy they are to locate.
Also, they should all be unique, not like B/W's Djinn bros, or the Musketeers. If they start having similar ones, I'd just rather get a few unique ones.
